Mild Tuesday, But Below Avg Temps Return Wednesday

High pressure will keep Southern New England "mild" and dry today.  A cold front will deliver Arctic air to the region for Wednesday and Thursday.  Strong winds will combine with the low air temperatures to deliver a few days that feel more like mid-January and not late March.  The astronomical and meteorological calendar tell us it is now Spring, but mother nature has other ideas.  Maybe by the time the Sox break camp, it will feel like the second season.

General Overview
Temperatures this morning are running in the low to mid 30's.

An upper-level disturbance will track across SNE later this AM/early PM which will enhance cloud cover for a period.  For much of the day there will be a mix of sun and clouds.  Light winds will increase to 3-7 MPH out of the west.
WPC Surface Fronts/Precipitation Tuesday 8 PM
The Arctic cold front will cross the region tonight.  The FROPA (frontal passage) will be dry, but NW winds will kick up behind the boundary.  Low temps tonight are forecast to drop into the low to mid 20's in the interior, while temps are in the upper 20's/low 30's in SE MA/RI.

By Wednesday AM strong high pressure is descending into the Upper Midwest.  A wave of low pressure may develop in the Gulf of Maine which will help to enhance the pressure gradient across our region.  Pockets of damaging wind are expected to develop, much like some of the other brutally cold/windy days seen so far this month.
WPC Surface Fronts/Precipitation 8 AM Wednesday
Max temperatures tonight will be in the upper 20's to mid 30's depending on location.  It will be colder in the higher elevations of Worcester County and Western MA and warmer in SE MA across the coastal plain.

Winds will gust 30-50 mph tomorrow.  That means the "Feels Like" temperature will be in the single digits/teens.  There is a chance a *Wind Advisory* will be needed.  Record low temperatures will be approached Thursday morning across the northeast.
Those New England records look safe, although Hartford will challenge that 9.  The Mid-Atlantic may have a better shot at some records from this air mass.

Temperatures will rebound Thursday afternoon and the wind will die down a bit. High pressure will move over the region and then offshore by Friday.
