Sunday forecast trends colder, wet snow possible in Md., Wv. mountains


GFS model indicates temperatures only in the 40s in Washington, D.C. at 2 p.m. Sunday

Some of the latest model guidance suggests temperatures will have a difficult time getting out of the 40s Sunday, with temperatures in the mid-40s during the afternoon, along with rain.


GFS model is forecasting a high of 53 degrees Sunday in Washington, D.C., which may be generous.

A NORTHERLY FLOW ALONG WITH PLENTY OF CLOUD COVER AND RAIN SUNDAY WILL MAKE IT FEEL MUCH CHILLIER WHEN COMPARED TO WHAT HAS BEEN OCCURRING OVER RECENT DAYS. MAX TEMPS MAY STRUGGLE TO REACH 50 DEGREES NEAR WASHINGTON AND BALTIMORE. MAX TEMPS IN THE MOUNTAINS WILL NEAR 40 DEGREES.

Recall a few days ago we talked about the GFS model simulating snow in Washington, D.C. Sunday. Well, it may not be that far off. You may only need to drive about 2-3 hours to encounter the white stuff.

High elevations in the the Laurel Highlands in southern Pennsylvania as well as the mountains of western Maryland (Garrett county) may see wet snow or mixed rain and snow, writes the NWS office in Pittsburgh:

DUE TO THE COLDNESS OF THE SURFACE LAYER...ITS POSSIBLE HIGHER ELEVATIONS MAY SEE A CHANGE TO LIGHT SNOW SHOWERS AT TIMES...BUT THE GROUND WILL REMAIN TOO WARM FOR ANY IMPACT.

Snow is probably most likely in some of the higher peaks of West Virginia, around Snowshoe, for example. Says the NWS office in Charleston:

TEMPERATURE FORECAST STILL HAVE US THINKING WET SNOW FLAKES COULD REACH THE HIGH TERRAIN MAINLY ELEVATIONS AT OR ABOVE 3000 FEET....COULD SEE A COATING OF WET SNOW AT THOSE HIGHEST ELEVATIONS.

While snow is exceptionally rare in D.C. in early October, it’s fairly common along West Virginia’s highest ridges, above 3 to 4 thousand feet. As the NWS office Charleston reminds us:

NOTHING UNUSUAL ABOUT THE FIRST FLAKES IN WV MOUNTAINS ON OCTOBER 7TH.
