Cold air that has been impacting the region for three days isn’t about to loosen its grip just yet, and most of the Greater Baltimore area will be in the single digits and low teens again early Friday morning. Winds out of the west and northwest Thursday did increase as expected, and it is still in the process of diminishing early Friday.
Therefore, it’ll “Feel Like” it’s in the teens everywhere for a while Friday morning, and then it won’t be quite as harsh after 8 a.m. Some early sun will tend to fade behind increasing clouds, and we’ll be turning the focus of our attention to a fast-moving, relatively weak wave of low pressure that will approach the mid-Atlantic states Friday afternoon. That will be our “snowmaker,” albeit fairly light and for only a period of four or five hours. Precipitation forecasts are now mostly around a tenth of an inch (the liquid equivalent), so we tend to think that — unless this system really “overachieves,” the snowfall accumulation totals will average 1-2 inches.
With the snow tapering off quickly Friday night, clouds will linger and most temperatures should wind up in the mid or upper teens. As the low pressure system responsible for the snow late Friday heads out to sea, it will begin to intensify just a bit. Therefore, while clouds early Friday should break for a fair amount of sunshine, there will also be a brisk wind out of the northwest that will average 10-20 mph with gusts of up to 25 mph possible. Temperatures close to 30
degrees will “Feel Like” they’re in the teens, and that wind will manage to die down Saturday night.
