Northeast

A fine, dry, sunny and near seasonal next 48 hours will dominate the Northeast today and Friday with high pressure firmly in control. Cool but not cold for New England with highs in the upper 30s while 40s bring comfortable conditions throughout the rest of the Northeast. Inland parts stretching from western upstate New York down to the Virginia-West Virginia border will warm to between 40-45 degrees while the Major Cities from Philadelphia up to Boston rise into the 45-48 degree range. Baltimore and Washington DC should top 50.

Overnight clear skies and light winds will mean a cooldown with the Big Cities falling to near freezing (32F) while suburbs and points west fall into the upper 20s. Low 20s for interior New England, near 30 for Boston, Providence and Hartford.

Midwest

Today and Friday will see little change due to a ridge of high pressure in control throughout the nation’s mid-section.

Lows tonight drop back into single digits to near zero with a chance of snow showers continuing.

Further south, it’s mostly sunny, dry and warmer than normal today. Temperatures are widely in the 50s across the Lower Midwest from Kansas City to St Louis up to Des Moines. Upper 30s to near 40 from Rapid City to Minneapolis to Green Bay. Chicago, Detroit to Cleveland and it’s at or slightly above 50.

Tonight: Lows drop back to the upper 20s, low 30s throughout the region. Always cooler across North Dakota, northern Minnesota, Wisconson and the UP of Michigan.

Friday: Warmer air reaches the northern region with mid-20s expected from North Dakota to the UP of Michigan. Staying mild further south with 40s and 50s for highs, decent sunny spells but rain will work north from the Southern Plains.
