Helsinki Hurricane: Finnish-type Frigidness
A. Camden Walker @ 12:15 PM
Prepare the clothing layers for the coldest weather to-date. It will be blustery. It will be bitter. The far northern territories (e.g. Finland, Siberia) with which Capitalweather.com chooses to analogize our current DC cold snap, could be exhausted soon at this rate...
Bitter Bombardment. 29° for a high temperature--with blustery chill rising from the single digits in the morning to the teens in the afternoon--is the warmest this new airmass can do for you. Sunshine will help warm you indoors, near insulated windows, but otherwise it will be useless. This air is extremely dry and windchills very low. Protect your skin. Cover your head, hands--and all extremities--very thoroughly. Where are my insulated ski pants?
Tonight, wind will ease up a little and shift to the southern direction ahead of our next arctic front. Skies will be cloudy after sunset and at dawn--with stars visible in between. Low temperatures will be in the mid-20s throughout most of the Metro Area.
Mild Mirage. Quickly we warm toward 50 degrees with southerly winds, but what awaits us behind this next cold front will erase all memory of this mildness. Still, a fairly nice day and sunshine to boot. Southern portions of our reading area may see mid 50s as high temperatures. Overnight, clouds increase as the front approaches, bringing a chance of rain or snow showers after midnight. Lows in the low-to-mid 30s
Tricky Frontal Passage. Rain showers may change over to snow showers before sunrise. There's a slight chance of minimal accumulation north and west of town especially on grassy surfaces (see Snow Lover's Crystal Ball below). We may quickly hit 43 degrees in the late morning, then temperaures falling through the 30s later in the day.

Next Chance of Accumulating Snow: Saturday Night-Sunday AM
Probability: 20%
Potential Impact:
Commentary: Our next arctic front moves into the area on Saturday evening. Late Saturday night into Sunday morning there is the potential for sprinkles or showers to turn into flurries or snow showers. With enough moisture and the right timing -- during the pre-dawn and early-morning hours -- there's the potential for a quick dusting to half-inch of snow north and west of town, especially on grassy surfaces, though chances are fairly low.
