FORECAST IN DETAIL


We’ve got snow in the forecast, but nothing like what we saw on Presidents’ Day weekend in 1979 or 2003. Yet, after a mild last few days, we’ll certainly be feeling the return to wintry conditions the next couple. Already missing that taste of spring we had yesterday? Glad we’ll see highs about 20 degrees lower today? The season of transition is approaching.

Today (Saturday): A storm developing off the Carolina coast should help keep us mostly cloudy or fully cloudy through the day, and it might even try to stall some snow/rain showers or light snow in the area (40-50% chance). The best odds of this activity should favor eastern spots, with any potential “heavier” activity probably closer to the coast or just offshore heading into evening. Thanks to highs heading for the upper 30s to low 40s, any snow that falls isn’t likely to accomplish much. Mood-enhancing flakes. Confidence: Medium

Tonight: The risk (30% chance) of snow showers (perhaps a dusting in a few spots if they hang around near/past sunset) continues until about mid-evening, mainly east of here. Otherwise, we see clouds breaking a bit and an increasing breeze from the northwest by morning. It’s a cold one, but not far from where we should be this time of year, as lows mainly reach the mid-and-upper 20s. Confidence: Medium

Tomorrow (Sunday): As the storm really wraps up while heading toward the Canadian Maritimes, we’re in between it and high pressure building in, which means we’ve got a fairly windy day on tap. Winds from the northwest blow up to about 20-25 mph with some gusts near 40 mph possible. Skies are partly cloudy, perhaps mostly cloudy at times, with snow flurries or snow showers possible (30% chance) through much of the day. This should be the peak day of our mini cold snap, with highs only making it to about 33-39. Confidence: Medium-High

Tomorrow night: After those cold daytime temperatures, clearing skies and calming winds should allow readings to fall to the mid-teens in the coldest spots and perhaps as high as the low 20s downtown. Winds slacken as high pressure builds in. Confidence: Medium-High

A LOOK AHEAD

Presidents’ Day (Monday) is dominated by high pressure drifting to by to the south and east, which should mean plentiful sunshine in the area and fairly light winds. Temperatures warm up slightly from Sunday, with highs ranging from near 40 to the mid-40s. Overnight lows are also tempered a bit thanks to a south wind, mainly ranging from near 30 to the mid-30s. Confidence: Medium-High

Tuesday features cloudy skies and a good chance for rain showers as a cold front approaches. While the main part of the storm system passes well to our northwest, we get a brief surge of warmer air out ahead of the front, and it sends highs to near or even past 50. Rainfall from this system shouldn’t too heavy, probably upwards of about 0.25”. Confidence: Medium
