A northern stream trough crosses the area Wednesday night. LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. Highs on Wednesday should be a few degrees above normal and around 5-10 degrees warmer than on Tuesday. Even with shortwaves embedded in the flow, the low to mid levels should be sufficiently dry to preclude any precipitation.
Lows Tuesday night should be around 5 degrees below normal, except up to around 10 degrees below normal in normally cooler valleys. Noting the expected mainly clear to clear sky and light winds, did opt towards the lower end of guidance for lows, with decent radiational cooling conditions expected. Northern stream shortwave ridging transits the area Tuesday night, with associated subsidence keeping things dry with minimal, if any cloud cover. Highs on Tuesday should be near to slightly below normal. Lows Monday night should be near to slightly below normal.Ī northern stream shortwave trough crosses the area Tuesday, however, with dry low levels, it should remain dry.
The low level flow will dry out this portion of the atmosphere, so even with shortwaves embedded in the flow, it should be dry, except for possibly some lingering showers over Downeast Maine early in the evening. The region is under SW flow at and above 700 hPa Monday night, with the flow becoming NW through the night below that. As the front moves through, expect breezy conditions with gusts up 25 mph. Temps around the low 70s on Monday could bounce around between upper 60s to low 70s if the NAM is to be trusted and the initial clear happens in the afternoon. All this ingredients is expected to produce isolated thunderstorms with the possibility of producing heavy rain. This could indicate initial clearing ahead of convection which could provide enough lift to produce thunderstorms. In addition, the NAM shows a thin line of theta-E moving through the region after the pre- frontal boundary pushes through. Upper air model soundings indicate very weak surface CAPE and low lapse rates, but positive Showalter index, long, skinny CAPE, and high PWATs near 2 inches. Rain showers are expected to end in the North Woods in the afternoon. By Monday, the cold front will enter the western edge of the area in the morning then quickly move through the region throughout the day. The upper level ridge will start to move to the E with the approaching cold front from the W tonight. Clouds will increase along with showers chances toward daybreak across the western zones. Showers ahead of a cold front are still mostly along or west of the Saint Lawrence River valley.
