Forecast Overview<\/strong><\/h3>\n

Relief is on the way following\u00a0a sweltering week of record-breaking temperatures experienced across the\u00a0Mid-Atlantic. Earlier this\u00a0week,\u00a0Washington Dulles International Airport\u00a0achieved a 3-day high temperature record streak (Monday through Wednesday) after breaking past\u00a0record high temperatures. Additionally,\u00a0Baltimore-Washington International (BWI) exceeded \u00a0 record temperatures on Tuesday and Wednesday. However, a strong sweeping cold front will generate much colder\/fall-like temperatures on Friday and Saturday. High temperatures will experience a bit of a roller coaster ride as they transition from 20 degrees above average\u00a0to 10 degrees below average (average high temperature for October is 67\u00b0F). The decrease in temperatures will accompany widespread\u00a0rain showers and cloudy conditions. The rest of the weekend will feature cool temperatures and brisk northerly wind breezes which could\u00a0produce\u00a0the first noticeable wind chills of the season.<\/p>\n

Thursday (Night)<\/strong><\/h3>\n

Mostly cloudy skies will lock in daytime heat and allow low temperatures to stay on the mild side as they subside into the mid-60s (the normal high for mid-October!). After midnight, an increasing chance for stray showers are expected to develop along with the potential for patchy fog. Light winds out of the south will provide a calm breeze around 5 to 10 mph.<\/p>\n

Friday<\/strong><\/h3>\n

As the cold front approaches from the northwest, widespread showers will occur across the forecast area during the early morning hours. Between\u00a02 p.m. and 4 p.m., abundant rain showers will continue to migrate into the College Park vicinity. Less than a quarter of an inch rain is anticipated while increasing amounts are likely to occur west of the I-95 corridor. Noticeably cooler daytime temperatures will decrease throughout the day after reaching into the upper 60\u2019s (east of the District) and low 50\u2019s (north and west of the District). Winds will shift from a light southerly flow (5 to 10 mph) to a breezy\u00a0northwest wind (15 to 20 mph).<\/p>\n

Saturday and Beyond<\/strong><\/h3>\n

As\u00a0high pressure builds in behind the cold front, the weekend will finally consist of\u00a0fall-like weather along with below-average chilly temperatures. On Saturday morning, leftover\u00a0showers will pass over the area\u00a0before cloud coverage decreases by the afternoon.\u00a0High temperatures will climb to\u00a0the mid-to-upper 50’s and low temperatures will range from the\u00a0upper 30’s to low 40’s. On\u00a0Sunday morning, the\u00a0wind-chill temperature will\u00a0dip towards the freezing mark (see image below). More specifically, cool overnight temperatures combined with blustery northeast winds (15-20 mph) will make it “feel” close to the freezing temperature (32\u00b0F).\u00a0By Sunday afternoon, clear skies will prevail and temperatures will peak towards the low 60’s.\u00a0Next week, dry and cool air will result from the combination of high pressure and a seasonable autumn air mass.<\/p>\n
