Sunny start to rainy week

High Pressure, Warm Front

High pressure centered over Lake Huron will drop south toward the Mid-Atlantic today.

Some early morning cloudiness is persisting across the region, but this should dissipate. Much of the day will turn out to the mostly sunny. Today should by far be the sunniest day of the week.

With the center of the high to our west, we will remain on the chilly, breezy east side of the high.

Northwest winds will gust to 30 mph at times today, keeping temperatures on the cool side. Most areas will not reach 50 degrees today, though some will come close. Higher elevations will stick closer to 45 degrees.

Overnight tonight, the high will develop along the coast of the Carolinas, allowing a warm front to head toward the Finger Lakes.

Clouds will increase tonight ahead of the warm surge, and a few showers or even flurries will be possible after midnight. Most areas will probably see little to no rain.

Temperatures will drop into the mid 30s this evening as the clouds start to increase. Steady or even slightly rising temperatures are then expected overnight.

The front will park itself over the region on Tuesday, allowing some warmer air in, but also keeping clouds plentiful.

A few showers will be possible from time to time, but especially in the late afternoon along and north of I-90.

Highs will be in the mid and upper 60s, and a few places reaching 70 in the southern and western portions of the region is not out of the question.

Rain Chances Increase

The front will push further north on Wednesday, allowing for warmer temperatures and some breaks of sunshine.

During the afternoon, the front will begin to sink back to the south with a sharp drop in temperatures. This leads to some inherent uncertainty in the temperatures, especially across the northern half of the region.

To the south, mid and even upper 70s are likely. To the north, 70s are still possible, but may be brief as temperatures begin to drop.

More widespread rain, and perhaps a few rumbles of thunder, will accompany the cold front Wednesday afternoon. The rain will spread from north to south late in the day and into the nighttime hours.

Low pressure will track along the front on Thursday, bringing high chances for rain throughout the day. Temperatures will again be dependent on the front but will most likely end up between 60-65 degrees for most areas, with a narrow belt of 55-60 degree temperatures possible.

By Friday, the low will be situated over northern New England, but not moving much. This should lead to on and off showers throughout the day. Gusty winds may also be possible.

High temperatures on Friday are a bit uncertain this far in advance, given the presence of the low pressure system. Mid or upper 50s look most likely at this time.

Precipitation should end by Saturday, but clouds and blustery winds will persist. Highs may struggle to reach the low 50s.

Sunshine should return Sunday with highs in the 50s.

Another surge of warmer air is possible next week with a good chance for 60s and 70s at least.
