High pressure will push in today and generate nice weather around here as we end the work week and begin the weekend. Another strong cold front, however, will whip through the region tomorrow night and it’ll turn much cooler for an extended period of time beginning Sunday. High temperatures today and Saturday will not be far from the 70 degree mark, but should generally be confined to the 50’s on Sunday, Monday, Tuesday and Wednesday. The cold front will primarily pass through on the dry side tomorrow evening; however, a shower or two cannot be ruled out; especially, in the western suburbs and the breeze will kick up noticeably late tomorrow and it'll stay quite windy tomorrow night and Sunday. Low pressure will drop southeastward from the Great Lakes region into the Mid-Atlantic by Tuesday and it could then strengthen along the east coast at mid-week giving us the chance for some rain on both Tuesday and Wednesday along with continued cool conditions. Elsewhere, Gonzalo weakened a bit overnight, but it remains a major hurricane (category 3) this morning with sustained winds at 130 mph and it makes its closest approach to Bermuda today bringing with it hurricane-force winds for several hours and a strong storm surge.
7:00 AM | Still somewhat unsettled today…big improvement on Friday and Saturday, but much cooler stretch begins on Sunday
Mostly cloudy although there can be a few peaks of sunshine, not as warm as the past couple of days, still the good chance for residual showers, highs near 70 degrees
Mostly cloudy, turning cooler late, maybe a shower or two, low 50’s towards morning

Partly cloudy, cool, low-to-mid 50's

The powerful cold front that generated heavy rain around here late yesterday and again last night is now pulling away from the region to the northeast, but it’ll stay somewhat unsettled as the upper-level low associated with the surface front passes nearby. Big improvement comes for tomorrow and Friday as high pressure returns to the region, but it turns quite cool beginning Sunday for an extended period of time following the passage of another cold front. High temperatures from Sunday through Tuesday of next week will likely be confined to the 50's in much of the I-95 corridor.
Elsewhere, on the tropical front, Gonzalo has reached major hurricane status (category 4) with sustained winds at 140 mph and is bearing down on Bermuda with a serious hit expected there on Friday. It is the first Atlantic hurricane to reach category 4 status since 2011 (Ophelia). Fortunately, the US mainland has not been hit by a major hurricane since the crazy year of 2005 - the longest stretch without a major hurricane in the US since at least the year 1900. In the Pacific Ocean, Tropical Storm Ana is likely to miss Hawaii to the south later this week.
An active cold frontal system supported by vigorous upper-level energy will generate heavy showers and potential strong thunderstorms in the I-95 corridor into early Thursday. Heavy rain on the order of 1-3 inches has the potential to create some localized flooding problems during the next 18 hours or so. The heaviest and steadiest rain will end by early tomorrow, but residual showers are possible later Thursday as the powerful upper-level low associated with this dynamic system passes nearby. High pressure will bring improvement to the Mid-Atlantic region as we close out the work week and begin the weekend with the return of some sunshine, but it'll turn noticeably cooler for Sunday and Monday.

An active cold frontal system supported by vigorous upper-level energy will generate heavy showers and potential strong thunderstorms in the DC metro region from later this morning into the overnight hours. Heavy rain on the order of an 1-3 inches has the potential to create some localized flooding problems and scattered strong thunderstorms are possible during this upcoming heavy rain event. The heaviest and steadiest rain will overnight, but residual showers are possible on Thursday as the upper-level low associated with this dynamic system passes nearby. High pressure will bring improvement to the Mid-Atlantic region as we close out the work week and begin the weekend with the return of some sunshine, but it'll turn noticeably cooler for Sunday and Monday.
