Periodic Rain and Showers Before The Warm Up
The main batch of rain moving through this morning will gradually be pushing off the coast this afternoon with rain tapering to showers. Temps will be warming aloft, but remain cool at the ground with breezy SE winds with the falling rain. Highs will remain in the 40′s with a slight moderation by the end of the day with lingering showers, drizzle with highs nearing 50.
Low pressure will be tracking into Canada tonight bringing it’s cold front through New England. This front may trigger a few more scattered showers after midnight with lows in the 40′s. By dawn tomorrow, clouds or an early shower south of the Pike…but drier air will be on the move for Easter morning! Clouds will be erodingalong and north of the Mass Pike as weak high pressure builds in. So the morning into the midday should turn out fine with breaking clouds, some partial sun inland. With a mild start, a light west wind and temps in the 40′s at dawn…with temps at 50 at 10-12 , this should be enough to pop temps well into the 60′s…and may even approach 70 with any sort of substantial sunshine through the midday. Weak sea breezes may keep it cooler at the coast.
The problem here is that Sunday will feature a cold front stalled over the area with clouds which will fill in after any morning breaks. This front will provide just enough lift to trigger a few more showers in the afternoon, especially along and south of the Pike. These will be brief and passing.
The cold front will then stall along the south coast overnight. Winds will be shifting from the west to the NE. With West winds transporting warmer air aloft, and cooler air off the ocean…the overrunning clouds will remain Sunday night into Monday…locked especially across central and southern New England. Easterly wind will make for a cooler and cloudy Monday with 50′s at the coast and some lwr to mid 60′s away from the onshore winds in western New England. The stalled front will begin to push north Monday Night in the form of a warm front which will become the focus for a few more showers Monday Night into early Tuesday.
How quickly the warm front can push through always remains a bit tricky in this region as the cold dome in NNE is always a little slow to budge. Clouds and showers across the north will give way to partly sunny skies where the warm front pushes through with temps climbing into the 70′s….with the warm spot likely being western MA, and the CT river Valley. Clouds may hang tough in NH to keep it cooler. SW winds will also keep in cooler in southeast MA…but still be mild in the 60′s to near 70 with increasing sun.
We will bask in the warm air through the midweek as SW winds aloft ahead of an approaching trough will transport unseasonal warm air into the Northeast with breezy SW winds. There will be some low level clouds to deal with from time to time…so I would not expect picture perfect weather…but at least it will be mild. Any sort of significant sun could allow our temps to spike to near 80…but because of expected cloud cover I have kept the expected midweek temps in the Lwr-mid 70′s with the warmest air inland away from the coast.
The next front will be pushing through late Thursday and Thursday night with showers and thunderstorms. Temps should remain mild Thursday in the 60′s and 70′s despite the plenty of clouds and the eventual showers.
drier air moves in for Friday with increasing to kick off the final weekend of April with temps holding in the 60′s. The good news is despite all the clouds and periodic showers…at least there are signs of some warmth for once after a cool April!
