[FREEZING FOG THREAT WANES AS THE MORNING WAXES… SHOWERS MOVE INTO THE REGION BY MID TO LATE AFTERNOON, ESPECIALLY EAST OF THE I-91 CORRIDOR WHICH LASTS INTO PART OF TONIGHT… A DRY COLD FRONT PASSES TOMORROW AFTER A MILD START… COLDER FOR MONDAY THROUGH THURSDAY… MONDAY COASTAL SYSTEM BRINGS RAIN AND SNOW TO THE REGION, MOSTLY SOUTH OF THE MASS PIKE IN MA AND CT… SOME LIGHT ACCUMULATIONS POSSIBLE… COLD AND BLUSTERY TUESDAY, WITH A MAJOR SNOWSTORM STILL POSSIBLE FOR THE ENTIRE REGION WEDNESDAY NIGHT INTO THURSDAY… 8:35AM SAT]

Good morning folks, has anyone experienced freezing fog this morning? Patchy dense fog continues across the region, though it will thin out and dissipate in some areas, and hang on in others.

This is because warmer air is going to be riding up and over the top of a slow drain of surface cold from north to south in our region.

Highs today, therefore, shouldn’t rise much beyond the upper 30s to near 40º under cloudy skies, with some fog patches around.

This afternoon, a weak low will develop along a warm front that tries to push north through our region, but won’t be able to fully do so until tomorrow.

Expect scattered showers to track northeast into WMass, northern CT and CMass, with the heaviest showers staying east of the I-91 corridor this afternoon and tonight. Rain should abate by midnight, lows will remain steady at the 35-40º range with patchy fog late.

For Sunday, we’ll briefly enter the warm sector of this storm passing to our northwest and while mostly cloudy skies are expected with our cold frontal passage, highs will reach the upper 40s to low 50s, so at least we’ll get a mild day in here before the Arctic hammer drops us into wintry pattern for much of the week. Lows Sunday night will dip into the upper 20s to low 30s.

For Monday, a coastal storm will be exiting east-northeast off of the Mid-Atlantic coastline. This looks to be packed with moisture, but likely stays a bit further south, bringing a mix of rain and snow to areas along and south of the Pike, with a few mixed showers north of there. Some light accumulations are possible, especially in the high terrain of northwest and northeast CT. Highs will be in the mid to upper 30s, with lows in the low to mid 20s.

Behind that system, cold air dumps into the region, with highs under mostly sunny skies only in the upper 20s to low 30s on Tuesday with blustery northwest winds.

Tuesday night will be the coldest night of the new cold season! Lows will plummet into the upper single digits to mid teens!

Now THAT is the kind of air mass you want to see ahead of a coastal storm to get a legit snowstorm in our region.

For Wednesday, highs will only be in the mid to upper 20s with clouds increasing, and snow possible by evening.

At the moment, we don’t know how this potential storm will track, but we do know that it has already formed and is entering the west coast of the U.S. soon.

We don’t need two pieces of energy to form a storm over us – this one is fully fledged already.

As of now, Wednesday night into Thursday look snowy, and we could get a serious snowstorm, so stay tuned for updates as we get closer.

Have a great day!
