High pressure to dominate the weekend High pressure builds in as an area of low pressure moves out of the state today. Saturday will be dry, but foggy in the morning as high pressure dominates the weather pattern. But then high pressure quickly moves out of the region as another frontal system approaches from the west on Sunday, reigniting rain chances. A cold front moves through on Monday with the heaviest rain from the system along with a few thunderstorms. Then an upper-level ridge builds in behind the cold front into the middle of the week, keeping us dry but warming things up again. Foggy starts likely for Saturday and Sunday With high pressure in control, clear skies and calm winds over the next two nights are the ideal conditions for fog formation. Early morning fog along the coast, in the mountain valleys, and along water tributaries can be expected, which could be locally dense. Visibility may be reduced to less than a mile and may be hazardous for driving and boating. The ground stratus could be stubborn in the usual locations along the MidCoast and DownEast areas and may hang on until late morning. Once the fog dissipates, mainly clear skies are expected, with comfortable temperatures to enjoy some time outside! Showers and storms possible Monday Monday 2 AM (06z) to Tuesday 2 AM (06z) - Well, it wouldn’t be summer without some more rain! A new frontal system approaches from the west later this weekend. A warm front will pass through the state late Sunday evening. This will reignite shower chances across the state. But the bulk of the rain will arrive on Monday as a cold front passes through the state. With a decent amount of instability in the atmosphere during the afternoon, a few thunderstorms are also expected; however, severe weather is not anticipated. With a lot of moisture in the atmosphere during the day, some heavy downpours are expected, which may lead to some localized flooding, especially in areas that flood easily. Heat builds starting Tuesday Despite a cold front moving through, temperatures and the humidity will actually increase as we head into the middle of the week. This is because of a critical summertime weather feature: the Bermuda High! An area of high pressure is off to our east, clockwise flow around it leads to southerly winds dominating mid-week. This will transport warm and humid air from the south into the region. While temperatures won’t be nearly as hot as they have been the past few weeks, it will still feel warm and sticky out there. High temperatures will be in the 80s across the state, with a few 90s possible in the far south. Dew points will be in the mid to upper 60s. Which will make the air outside feel a little warmer than it actually is. Temperature outlook through Thursday Today's update prepared by Penn State student intern |
