The mountains and north could get isolated storms
Given the lack of atmospheric forcing with the frontal boundary, the chance for severe storms has been reduced to isolated for western and northern areas. As I stated in my update yesterday, what is likely to occur are slow moving pulse storms which could bring flash flooding from heavy rain. Southern and western areas may get a shower around midday ahead of the frontal approach in the afternoon. It will be a "weather you can wear" type of day as dew points climb into the 60s to perhaps the low 70s for southwest interior areas. It will be uncomfortable, but short lived.
Coastal areas may see some fog Saturday morning, but as the northwest breeze picks up, that should blow out by mid-morning, with a nice day on tap statewide.
More showers on the way Monday into Tuesday
This loop gives a general idea of what to expect precipitation wise through early next week. After the cold front slides through on Friday, it will be a dry, but cool weekend. Clouds will be on the increase from west to east Monday and showers are in the offing Monday into early Tuesday. We could have another rain event for the middle part of next week.
Given the lack of moisture from the southwest, these rain events next week are likely to be scattered in nature. When systems approach us from the northwest, there generally isn't a whole lot of rainfall that comes out of these. As like the clipper snow makers in winter, there is often little moisture to work with and the impacts are minimal for most.
And yes, your eyes aren't deceiving you... yes, that is snow (blue shaded) in the forecast for Newfoundland over the weekend. The cold air continues to lurk to our northeast. Mother Nature could care less that the calendar is about to flip to June.
Outlook through Tuesday
If you like the heat and humidity, Friday will be your day. The cooler trend that occurs after that will be with us for the next several days. June appears to be on the cool and generally dry side for much of the northeast through the first half of the month. Summer may show up on it's official astronomical start date come the third week of the month.

Muggy weather returns
Thursday sees the humidity gradually increase during the day and into the evening. High pressure keeping the region cool and dry appears to be a bit stubborn in departure, which may keep the sultry air away from most of the region until after night fall. Friday will certainly be a sticky affair, but it will only be for a day as drier air returns on Saturday.
Storm threat for Friday
This loop here is from the NAM-WRF model starting at 5 AM Friday until 7 PM. This is rough idea of what to expect for timing and type. As time grows closer, a few things can be ruled out. Tornadoes and damaging wind do not appear to be factor. These storms appear of a pulse variety, which with little upper air wind means what storms form will likely move slow and cause flash flood potential rain in isolated areas.
As discussed in yesterday's update, there will be plenty of moisture, along with convective energy and cooler temperatures aloft that will touch off showers and thunderstorms, mainly in the afternoon into the wee hours of Saturday morning. There could be a few isolated showers around daylight along the coast, but those appear short lived and the region will clear out during the day. I am not going to rule out severe potential just yet. Anytime there is tropical air with cold air bearing down on the region, there is the threat for strong storms.
Stay tuned for updates.
The bowling balls continue to roll
After the warm up late week and cool down over the weekend, it appears that even cooler air is likely to start off in June. While it is early to tell, the gardeners and farmers will want to pay attention to frost threats in the middle part of next week. After that, a ridge appears to build in to warm the region for the second full weekend of June.
Drought concerns rising
Without question it has been a very dry spring for western and southern areas, and abnormally dry for eastern areas of the state. Northern Maine is down on rainfall for the month, but for the season is only off fractionally or in the case of Caribou, showing a surplus. All areas of the state are running below average for May, and it will end that way as the month closes out on Thursday.
Numbers not shown in the graphic but worth noting, our neighbors in New Hampshire are feeling the effects from the dry conditions, also. Manchester has only recorded 0.77" of rain for May and is down 2.97" from it's monthly average of 3.74". Concord has received slightly more at 1.01" for the month, off 2.39" of its average of 3.40". Seasonally (since March 1st) Manchester is down 4.29" and Concord is off 2.17" from normal. This information, along with the deficits for Portland and Augusta indicate the lack of rain is affecting much of southern New Hampshire, and is a regional problem for central New England.
The outlook for the first couple weeks of June aren't showing much relief from the drought conditions, either. For those who depend on well water, you should be conserving supply if you have not already. For the hikers, campers, those who want to burn off brush or have a bonfire, you need to stay in touch with the Maine Forest Service and local fire departments for permits and information. Wildfire concerns will persist until meaningful rain comes, and that could be awhile.
Outlook through Monday
Outside of a couple of minor adjustments to temperatures, the forecast hasn't changed much heading into the weekend. With the increased humidity, fog could be a concern for coastal areas Friday morning. I will keep the threat for severe storms in the forecast and may alter that in my update tomorrow pending on overnight data and review of conditions to the west.

Roller coaster weather pattern continues
After another dry day Wednesday, a southwest flow ahead of a cold front drives the humidity levels high Thursday night into Friday. Showers and thunderstorms develop Friday as the front moves through the region. A back door cold front sinks south late Friday, providing a dry but cooler trend for the weekend.
Severe potential from Alberto remnants late week
Folks statewide should stay in close contact with the forecast in regards to Friday for severe weather potential. A frontal boundary containing rich remnant moisture from Alberto moves westward during the day. Storms could bring frequent lightning, flash flooding, gusty winds and hail. Time will tell if tornadic features may also be a concern. PLEASE stay updated on the forecast.
Dry times continue...
Outside of the northeast corner of The County, most of the state is well below normal for rainfall. Some areas did pick up some Saturday evening from the recent front that passed through, but many areas didn't see much, if anything. Southern areas remain on pace for the second driest May on record, a mark likely achieved as the month ends on Thursday.
I wish I had better news to report on the prospects for rain. The rainfall idea from the Weather Prediction Center Tuesday morning shows some liquid on the way late week from the Alberto remnants, but this is only a rough idea. Knowing the front will be tropical in nature may provide some heavy rain in areas, but some areas may escape with low end amounts. The next chance for a widespread rain event appears next week, but that is a low confidence idea for now.
Regional Outlook through the weekend
In the past, I have issued two separate forecast panels to cover regional outlooks. At times I found it to be difficult to be more accurate for the region due to varying conditions. This graphic I am testing for now to see if it is going to work. I would like feedback from you on whether you like the new presentation. My own self critique indicates that it is a bit busy, but it does do the job to allow me to become more specific for the region.
The only mention on this outlook worth mentioning is I expect a coastal sea breeze on Saturday that will likely keep the shorelines of the south and east in the 60s. Other than that, the forecast for now looks good for each area.

The unofficial start to summer is upon us
I was sorting out some graphics and feel confident at this point to put the winter icons to rest. The region isn't out of the range for frost threats, but the snow idea is over. That noted, areas of Newfoundland picked up over a foot of the white stuff on Wednesday, and areas of northern New Brunswick saw some accumulation as well. While that is going on, there is a tropical system forming off the Yucatan Peninsula. While Friday will feel like summer for Maine, by Sunday the region will feel a temperature whiplash with highs only in the 50s and 60s. Ah, spring!
The weekend appears in fair shape
Spring is known for back door cold fronts in this part of the planet, and that is exactly what is on tap for the weekend. The front sags from the northeast to the southwest Friday into Saturday bringing a chance for showers and thunderstorms. The front stalls to the south on Sunday, which will bring a decent but cool day for the north and east, which clouds persist over the south and west. Monday appears foggy and drizzly for the coastal plain, with a risk of a shower everywhere as the front moves through Monday afternoon into early Tuesday. Temperatures increase as we head into the middle part of next week.
Weekend not a washout by any stretch
Due to the change in forecast with the front sagging further to the south, what appeared as beneficial rain earlier in the week has backed off on that idea considerably. The mountains and north will get some, while much of the coastal plain won't see a whole lot of precipitation over the next week.
Our first tropical system of the season
For folks with interest in the eastern and central Gulf coast region, consider this a public service announcement for you. This is for informational purposes only, and is by no means an actual forecast. Guidance is indicating the first tropical system of the season forming over the weekend and making landfall in the central region roughly Monday or Tuesday. Whether or not this system becomes named as Alberto time will tell, but there appears to be a good chance that it will. How strong the system will get remains in question. At the very least it will bring potential for flooding rainfall to parts of Florida up into Georgia, Alabama, Mississippi, and southeastern Louisiana, along with the Carolinas. As always, stay in touch with the National Hurricane Center for the latest official forecast information, along with the local National Weather Service office for the region where you have concern.
5-Day Outlook - Coastal Plain
Saturday starts off dry with some sun which will allow temperatures to rise up in the 70s before the back door cold front drops down and kick off some showers in the afternoon. Sunday and Monday are likely to be mostly cloudy affairs, and cool. Memorial Day appears to be a fog/drizzle situation for much of the coast, with light scattered showers as frontal boundary approaches from the west later in the day. Skies clear out Tuesday, and temperatures gradually rise as the week progresses.
5-Day Outlook - North Country
For the most part, the north country gets the better weekend, especially for the Crown. After the showers pass through Saturday morning, it appears dry until the afternoon on Memorial Day. The north will see more sun and warmer conditions on Sunday, with some areas of The County pushing 70°. With the front from the west pushing through on Monday, that will be the cooler of the three days ahead. Another front approaches the far north later in the week.

Region is caught in a pickle
The battle between cold and warm continue over the North American continent and New England appears to be in cross hairs of it over Memorial Day Weekend. Six upper level lows are sandwiched in between three strong ridges, and the result is a frontal boundary that appears to wobble over New England beginning Friday for northern and eastern Maine, then sagging south and westward for Saturday and the rest of the weekend.
The weekend does not appear to be a total loss. Showers appear light to moderate at times, but scattered and intermittent. It all depends on region and time of day. For those that are camping, expect shower activity at night Friday, Saturday and Sunday.
Dry times indeed
As stated with regularity this spring, wildfire concerns have ran high due to the lack of any meaningful rainfall. With the foliage blooming, it calms the threat a bit, but much of the region is still very dry.
The only area where rainfall has kept close to normal in May is that in Houlton where they are currently running 0.09" deficit. Frenchville (-1.03"), Augusta (-1.64"), and Portland (-2.09") are the state's driest areas that have any long term recorded history. In fact, if the month ended today, this would be the second driest May on record for Maine's largest city with only 0.75" of rainfall recorded at the Jetport.
The region could use a good soaker. We'll have to watch the Gulf of Mexico for next week to see if the area can tap into some of that moisture. The shower activity over Maine this weekend will bring some rain, but may not make much of a dent in the current monthly shortfall.
Soggy for much of the Eastern United States
Rainfall total idea for the eastern half of the country through the weekend shows heavy rain over the southeast from tropical influence. A disturbance is being monitored by the National Hurricane Center for possible development. At this point, it appears that it is more of monsoon rain maker than anything else. With the frontal boundary meandering over New England, there is a chance for some beneficial rain. This idea may be a touch overdone, but 1/4"-3/4" is a reasonable total for much of the state between Friday and Monday evening.
5-Day Outlook - Coastal Plain
It will feel like summer Friday with widespread 80s. With dew points in the upper 50s / low 60s, it could feel a touch humid in areas, but generally warm and comfortable. Saturday, the warm area appears to be eastern Maine where the sun breaks out, whereas southern areas will stay on the cool side (50s / 60s) and deal with showers activity. Off and on showers will persist as the frontal boundary hangs around through the remainder of the weekend.
5-Day Outlook - North Country
Thursday will be touch cooler for the north as clouds dominate the skyline with a weak boundary sliding southeastward from Quebec. Friday will be showery for the north, with much of the western mountains staying dry. That equation flips on Saturday, with cooler, damp conditions for western areas, where The County stays dry. Off and on showers for both regions are possible the remainder of the weekend.
