Today is starting off brisk and cold under a clear to partly cloudy sky... With most temperatures expected to be in the 20s at daybreak, the wind out of the west and northwest will average a sustained 10-20 mph... And gusts of up to 30 mph locally will make it "feel like" it’s in the single digits and teens...
The wind should linger throughout much of the day, because while the global models are showing that the pressure gradient between a storm in the Canadian Maritimes and a high pressure system over southern Ontario will be relaxing by the end of the day (meaning that winds should start to subside by nightfall), today will still be a good day to have the hat, scarf, gloves and everything in your 'winter weather arsenal' handy to combat the chill...

Most actual temperatures will be in the mid or upper 30s, which is approximately five degrees below the seasonal averages...
As we've been discussing all week, there will be dry weather for the balance of today and tonight, and this should last through most (if not all) of tomorrow... The high pressure ridge that is going to be building down from the north is going to be pressing southward along the Appalachians, driving a 'wedge' of dry air as far south as northeastern Georgia...

Therefore, after a clear and cold night with much less wind and temperatures in the teens in the typically colder spots and the 20s in the larger cities, tomorrow will get off to a fairly bright start... It'll take a while for clouds to gather and thicken, and daytime temperatures should rebound a bit from recent lower-than-normal levels...
As some mild and moist air limps northeastward late tomorrow and tomorrow night, we're still expecting there will be some period of light precipitation occurring... It is going to have to fight off quite a bit of dry air being supplied by that high pressure system of Canadian origin, but a little rain, or a mixture of rain and snow is likely... Most places will get it AFTER MIDNIGHT, and temperatures should be no lower than the 30s...
There is more of a consensus being built now regarding the area of low pressure that will be emerging in the mid Atlantic states on Saturday... By and large, it'll be a secondary wave that will form tomorrow night as a primary wave of low pressure in the Great Lakes begins to weaken...
This is the same wave of low pressure that will be responsible for a widespread area of snow and ice in the Plains during the next 24 hours... Even though there could be some wet snow mixing with rain on Saturday in some areas located well north and west of the I-95 corridor, the odds seem to favor that the bigger cities and the coastal plain will just get rain much of the time, and temperatures should reach the lower or middle 40s...
The wave of low pressure that should be located near the Virginia Coast on Saturday morning is going to move into a position east of Cape Cod by late Saturday night or Sunday morning...
Therefore, we're inclined to think that a major winter storm is going to have an impact on eastern New England during the second half of the weekend (which would mark the third weekend in a row that Boston would see some kind of snow, whether it be measured in 'inches' or 'feet')...
But, for areas farther south and west, Sunday just looks like it will turn out partly sunny and windy in the afternoon... We are still allowing for a period of rain, or wet snow during the morning around here, but can easily envision how all precipitation could be removed from Sunday's forecast in the not-too-distant future...
Temperatures should be mostly in the 40s early next week, and we'll have some additional opportunities to see some rain...
Have a good day!!!
