Inbound High Pressure

Today will be a day of transition as low pressure pulls away from the area and a high pressure builds in to take its place.

Rain showers linger across the region this morning with the center of the low along the coast of Massachusetts. The rain will slowly end from west to east and should exit the region completely by midday or the early afternoon.

The rain this morning will be much lighter than much of the rain that fell yesterday.

Skies are clear this morning as close as southern Ontario and Ohio. This clearing will also move east and should overtake our entire region by the late afternoon.

Temperatures will be warmest today where it is sunniest longest, that is in the western half of the region. There, highs should break into the low 50s.

Further east, highs will be in the upper 40s with mid 40s along and east of I-81, except in Syracuse where a run at 50 degrees is likely.

Clear skies tonight will allow temperatures to fall back to near 30 degrees.

Tuesday will be a sunny day with temperatures nearing seasonal norms. Many places should be in the upper 50s to near 60 degrees. A few afternoon clouds will mix with the sun, and a stray shower cannot be totally ruled out, mainly west of I-390.

Mid-Week System

The next weather maker will begin to approach our area on Wednesday.

Dry air associated with the high pressure system should keep our area mostly dry on Wednesday. Sunshine will mix with clouds and a late day shower will be possible.

Winds will turn to the southeast and increase, with gusts over 30 mph possible.

Southeast winds favor warm temperatures in the I-90 and I-390 corridors as the air slopes down off the higher elevations to the southeast. Highs in these areas should break into the low 60s on Wednesday. Upper 50s are likely elsewhere.

Rain showers will increase Wednesday night and into early Thursday. A band of heavier rain is possible Thursday afternoon, perhaps with a rumble of thunder or two. Temperatures will remain near 60.

Winds will peak ahead of the rain band with gusts of 40-45 mph, still from the southeast. A few higher elevations could gust to 50 mph. Once the rain moves through, winds will drop dramatically.

Friday may have some lingering showers behind the low pressure system, but some breaks of sunshine are also expected. With a lack of cold air behind the low, highs should again range somewhere between 55-65 degrees.

Warmer weather is expected through the weekend, but below normal temperatures are likely for next week once again.

    Drew: close to two inches of rain yesterday through last night here in Enfield. Creek was quite high but not too threatening. If the heavier rain had continued throughout the night flooding would have been probable in spots. If I’m not mistaken National weather had called for half inch or so? Thanks for your hard work.

      Hi Terry, thanks for the report! I am not aware of what the NWS had predicted. I wasn’t able to update this weekend as I had planned, so I didn’t pay too much attention to what the models were showing as for rain amounts. I was, personally, surprised at just how much rain fell where I was. Lots of big puddles in the yard!
