The sky starts off mostly sunny for the state, but clouds will be on the increase this afternoon. Most of the day stays dry. Shower break out over western and southern areas by early evening, As the warm front progresses northeast, showers and chance for overnight thunder overspreads the state. Showers taper off as we head into Sunday, with the last of the rain activity departing DownEast areas by mid-morning.  With the warm air mass in place, expect humidity levels to rise, and expect areas of fog, some of which could be locally dense to start Sunday.

A cold front drops down from the northeast Sunday afternoon and will bring a chance of widely scattered showers and thunderstorms along with it. The front should clear the state Sunday night. High pressure arrives for Memorial Day, bringing nice conditions statewide to wrap up the holiday weekend. 

For most areas, rainfall amounts through Monday appear to range in the ¼-½" range with locally higher or lower amounts with downpours. The higher mountain regions could see upwards of an inch of liquid by the time the last of the showers pass through Sunday evening. 

Severe weather potential remains very low, but there is always a chance for it to occur. It would still be advised to keep an eye to the sky and plan to seek shelter when thunder is heard. Along with lightning, expect gusty winds and downpours in any thunderstorm that forms.  

Temperature range through the period... Saturday sees widespread 70s with 60s for the ocean shorelines. Overnight lows fall to around 50°. Sunday sees northern and DownEast areas ending up on the cool side with 50s to around 60°, 60s for Bangor on up into the central highlands and Greenville, and 70s for southwest interior, cooler once again for the shorelines. Overnight lows fall back in to the 40s for the western mountains, north and DownEast, 50s for the southwest interior and Bangor. Monday's highs range from around 60° for the mountains and north, 60s for DownEast areas and 70s for the southwestern areas.

Have a great weekend, and stay safe!

Showers end from west to east Friday morning. While the surface low departs, the upper level low appears to be a bit slow in moving out. That will cause for varying amounts of clouds, with a chance for a sprinkle or spot shower through this evening. Pockets of dense fog are possible this morning, but should clear out around mid-morning.

As the surface low departs, it will intensify as it heads into Atlantic Canada. Northerly winds increase bring Flying Trash Can Alert levels with gusts reaching 40 mph in areas through tonight.  As the low moves eastward, wind will taper off into the overnight. High temperatures for the day appear to be around 60° statewide, coolest along the DownEast shores where 50s are likely.

Saturday starts off mostly sunny for the state, with clouds on the increase through the day. Showers associated with a warm front are likely to break out in the late afternoon for western and southern areas, early to mid-evening for northern and eastern areas. Showers will continue overnight into early Sunday. After the warm front passes through, southern areas could see an uptick in humidity, which may be in the form of fog in areas to start off. A cold front approaches the area Sunday afternoon, which will bring another round of showers statewide and possibly a thunderstorm for western and southern areas through late afternoon. At this point, any severe weather threat Sunday is very low. 

Memorial Day is on track to be a nice one, with sun and seasonable temperatures. 

Showers return to all but northern areas of the state on Tuesday as low pressure passes through western New England. A long wave frontal boundary approaches the region on Wednesday, which may bring an afternoon shower for western and southern areas. Thursday appears to be a wet one as that frontal boundary passes through the area.

Folks getting an early jump on holiday weekend camping trips should be on notice that isolated thunderstorms are possible, mainly in the high country later Thursday into Friday morning. Potentially, they could pack downpours, localized flash flooding, and some gusty winds. The severe storm threat is very low. 

Most of the region stays dry into Thursday night before areas get showers and potential storms overnight. It will be a bit of a soggy start Friday morning in some areas, but the region as a whole should see improvement as the day progresses.

The trend continues that the weekend won't be total washout, but will be damp at times. Friday afternoon through Saturday afternoon appears dry for the region. Monday appears to be dry for the state, also. Sunday appears to be the wettest of the holiday weekend, with only northern areas expecting showers through the day.  Tuesday appears wet everywhere.

Western and eastern areas continue to remain on track to get the most rainfall with an inch or more through the weekend. Localized areas of higher or lower amounts are possible. If you are camping over of the holiday, pick your spot with rain in mind. 

While Saturday will be the warmest day of the weekend, Monday will be the driest of the three statewide. For folks travelling, please do so safely.

The region is back into a west to east zonal pattern which has been the main forecast track since last fall.  For those headed to campgrounds for the long weekend, make sure you prepare for periodic wet conditions.  The weekend won't be a complete washout, but will have its moments of showers. I am not expecting any form of severe weather at this point. 

Thursday morning may see a few light showers for northern and eastern areas. Western and southern areas will see clouds on the increase in the morning with showers breaking out Thursday afternoon. The entire region deals with  showers Thursday night. Southern areas get a chance for an early morning shower Friday. Northern, western and eastern areas have a chance for a brief shower activity through the morning, with a spot shower possible through the afternoon. 

Saturday starts off dry and with some sun. Clouds will increase once again, with showers breaking out in the afternoon. Saturday night will be another damp one state wide. Sunday, southern areas may see an early morning shower Sunday morning. Northern, western and eastern areas have a chance for a brief shower activity through the morning, with a spot shower possible through the afternoon. ​

Memorial Day starts off dry everywhere. Clouds will be on the increase during the day with showers breaking out over northern, western, and eastern areas in the afternoon. Southern areas may escape with only an isolated spot shower late in the day.  High pressure returns to the region and dries us out on Tuesday.

Southwestern areas appear to be on the dry end of projected rain amounts through the forecast period. The higher elevations of the western mountains and central highlands could potentially receiving the most rainfall from off and on shower activity through the long weekend. 

As both the surface low and upper low move eastward today, there could be a few showers for northern areas and some isolated showers for western and eastern areas. Southern areas appear mainly dry.

As the departing low intensifies in departure, the breeze will increase. The stronger gusts appear for western and and southern areas where 40+ mph is possible. High temperatures for the day will be a bit on the cool side, with 40s for northern areas, around 50 for the western mountains, 50s for eastern areas and 60s south.

We're back into the clipper pattern as we head into the Memorial Day Weekend. After a dry Wednesday and a dry start to Thursday, showers return Thursday afternoon into the overnight hours of Friday.  Friday looks fair with a southerly breeze forming which will keep the beaches cool. Clouds increase on Saturday with showers as we head into the afternoon. Sunday may start off with a shower in northern areas, but the rest of the region appears dry with a rise in temperatures.

Memorial Day itself may bring a slight chance of a shower as another weak frontal boundary works through the region. Congratulations... winter is officially over. Time to check the air conditioners and get ready for warmer times ahead!

As I have been mentioning on my Facebook updates in the past few days, the threat for storms has been concerning over the past few days. That potential appears to be reality for much of the region today. 

While Storm Prediction Center has highlighted much of western Maine in the "slight risk" category, there is potential that this areas could expand pending on daytime heating and frontal boundary progression. 

A refresher on the severe thunderstorm risks issued by SPC shows the levels and what they mean. While at first glance it may not appear to be a huge threat, the threat exists for some isolated intense storms which could pack a punch once developed. 

I have preached for years that NOAA Weather Radios properly set up to alert with warnings are the most reliable way to get storm related information. Maine is a rural state with cell phone coverage covering half of it. Of the half of the state covered, only two cell phone companies cover most of it, with other service providers in roaming areas outside of southern Maine.  NOAA Weather Radio covers almost the entire state. 

This is definitely an "eye-to-the-sky" and a "listen closely" day for the state. Northern areas may see some isolated rumbles this morning, it will be this afternoon for western, eastern and southern areas. It will be imperative to keep track of the latest forecast information through the afternoon and early evening as there is potential for watches and warnings.  This is our first severe threat of the season... STAY ON ALERT! 

There is plenty of spin predicted in the atmosphere over the region this afternoon into early evening. There is a risk of damaging wind, along with tornado potential. Given the cold air coming in with the front, large hail is a potential concern with this set up. With humidity levels elevated, the risk of localized flash flooding, hydroplaning on roadways, and reduced driving visibility are all hazards as well.

For those looking for spring... it has officially arrived. Summer is knocking to come in.

Any outdoor plans for Friday will be damp as a warm front enters into the region. Southern areas may see showers taper toward evening and catch a glimpse of sun as the day ends, but for the rest of the region, it will be raindrops into Friday night. A cold front sweeps it all away Friday night into early Saturday. Northern areas may see a few scattered showers to start Saturday morning, but those should be out of the way by around mid-morning. 

Rainfall amounts still appear to be in the ½-1" range, with lesser amounts for The County. 

Sunday appears to be dry for a bulk of the region, thanks to high pressure to the north. A potential NorEaster may impact the area Monday and could linger into the middle part of the week. Cold air may bleed in from the northeast and bring some wet snow to the mountains Monday night into Tuesday. Given the moisture content potential of the NorEaster, any snow that comes may bring a wet couple of inches on grassy surfaces and the rock of the higher terrain. I will stress that this is a LOW confidence forecast for now. High pressure that moves into the area this weekend may change the forecast track of the ocean storm. 

Stay tuned! 

Saturday will be another breezy one as high pressure moves into the region. Time will tell what happens the first of next week. We're roughly about a week away from seasonable temperatures. We'll be below normal on average until then.

Hopefully everyone got the memo to cover up any plants of value as there is potential for a heavy frost statewide this evening. The sky will start off mostly sunny in all locales on Thursday, Clouds will thicken as the day progresses. There is a slight chance for a sprinkle or a light shower over western and southern areas Thursday afternoon, but the steadier rain appears to hold off until Thursday night into early Friday morning. Showers will continue through the day on Friday, ending from west to east Friday evening into early Saturday morning.

All in all, most areas can expect roughly ½" of rainfall from this event. The higher elevations could see as much as an inch. I don't expect any flooding issues of concern with this system. 

Skies clear out on Saturday. It'll be another breezy one as high pressure moves into the area during the day. That area of high pressure may be strong enough to keep an approaching system south of the region for most of Mother's Day. I can't rule out a chance for a shower over southern areas late in the day.  High pressure moves eastward Sunday night and showers return Monday, and may linger into Tuesday.

For folks that have got a jump on growing season, you'll need to have the covers ready for action Wednesday night. Unless you can see or smell the ocean from your planting point, chances are good that you may see some frost on the ground come Thursday morning. The trend has been consistent on this idea for several days now. I expect frost and/or freeze advisories to make the weather headlines Wednesday. 

Another trend that has been consistent has been this long wave frontal boundary on the way for Friday. Looks like 1/2"-1" of rain is possible with this one. The day appears to be a washout at this point, with drier weather working in for Saturday. 

After a cool, breezy day on Wednesday and a chilly Thursday start, clouds increase ahead of the rain moving in for Friday. High pressure moves in Saturday and will bring breezy conditions and closer to seasonable temperatures. Mother's Day is in question for western and southern areas as for now there is a chance for afternoon showers, but confidence in that is low for now. 

I will update on that as the weekend gets closer.

Northern and western areas see shower develop in the morning, southern and eastern areas by the afternoon. Certainly not a soaker, but a few areas may see a period of steady rain for a time. Shower activity ends from northwest to southeast and will be over most everywhere by late evening.

With spring athletics and construction in high gear, it's now the time to pay attention to the clouds and listen for potential thunder. I don't expect anything in the manner of severe storms, but there is enough convective energy around to support of few rumbles, especially for southern areas Tuesday afternoon. Remember, when you hear thunder, it's time to seek shelter immediately until the threat is over.

All in all, not a whole lot of rain associated with this. Isolated areas may pick up as much as a 1/2", other areas may not get any measurable rain at all. For most, it may be enough to be annoying, and that is about it. 

Wednesday will be a breezy day statewide as Canadian high pressure builds into the area. The breeze settles Wednesday night, making frost possible for areas away from the coast. For those who got a jump on spring planting last weekend, you'll want to be prepared to cover any plants Wednesday night. Only areas exempt from this would be along the immediate shorelines and the islands.

Pardon me if you've seen this movie several times before this spring. Another long wave frontal boundary is in the forecast as we wrap up the work week. For now  it appears the timing will be Thursday night for western areas, overspreading the state by Friday morning, and ending in the wee hours of Saturday morning. 

Combined totals of both the Tuesday and Friday rain events range from a half inch or less in the north and east to around an inch for southwestern areas. There is no concern for flooding of any type as it appears for now. 

Below normal temperatures and slightly above average rainfall continue to be the main ideas in the pattern through the middle part of May. The pattern has already shifted to a drier one, with showers every third day. The weekend appears dry, with the next chance for rain possible early next week.
