After a Canadian high pressure system and a storm system combined today to make it a cold, cloudy and even a very snowy day for a good chunk of the area , we will see a gradual warm up to near to slightly above average for the Thursday through Saturday.
Tonight and especially tomorrow we will see partially clearing skies, with skies becoming mostly clear for the northern interior but staying cloudy in southern areas as moisture continues to stream from WSW to ENE over the SE US
For tomorrow the Canadian high pressure will move off the New England coast with a easterly wind developing, with that comes warmer conditions but also the threat for mostly cloudy skies to continue especially close to the coast, highs will moderate to the upper 30s to mid 40s
Wednesday will feature increasing clouds and eventually developing rainfall as a storm system develops near the Great Lakes , a trailing cold front will swing east and pick up moisture that will be lingering off the southeast coast from today’s storm, and as the trough turns negative Atlantic moisture will be pulled right into the area from SSE to NNW along with an area of low pressure developing along the coast
Showers will develop Wednesday afternoon and may become a steady heavy rain at night depending on just how much moisture interacts with the cold front and how strong the coastal wave of low pressure becomes
There is potential for a widespread 0.50-1.50 inches of rain, the lighter amounts will occur if we get late coastal development , higher amounts if it develops early
Either way the storm will exit by Thursday morning with temperatures moderating to the 50s for most of the area through Saturday as mild pacific air moves in from a zonal flow, lows will be in the upper 20s to mid 30s overall
Saturday a cold front will pass through the area as we see a reload of the same pattern we’ve seen since November , as a large ridge redevelops over the east pacific , a trough develops over the eastern 2/3 of the nation with a flow developing directly from the Arctic , and a piece of the Polar vortex comes south, there is potential for far below average temperatures and record cold which will begin coming in Sunday and last through next week.
We see the general pattern expected to take hold from days 6-14 and beyond , and obviously with this cold the snow threats aren’t done yet this year.
