Todays Recap:The weather today was fantastic, as highs once again neared 70 degrees in many locations, under nearly cloudless skies.
Short term Outlook:
The main forecast challenge for tonight revolves around the passage of a cold front. Regional visible/IR satellite reveals a deep plume of cloud cover extending from the Upstate of New York, southwestward into the Tennessee River Valley, all associated with an approaching cold front. Appropriately, NEXRAD (NEXt generation RADar) reveal some scattered light rain showers mainly west of the Appalachian Mountains.
With minimal lifting occurring in the atmosphere in association with this cold front, showers will have a difficult time traversing the high peaks of the Appalachian Mountain range overnight. Nonetheless, a small (20% or less) chance of precip is warranted tonight. Folks in western MD and the Shenandoah Valley have a significantly increased chance at light rainfall tonight.
Tomorrow: The effects of the cold front are short-lived as an upper ridge builds back into the region during the afternoon Wednesday. High temperatures will try to approach 70 in the District (although we likely be restricted to mid 60s).
Thursday: The upper ridge becomes fully entrenched across the region during the day, yielding mainly sunny skies, and will likely begin to warm us up again into the upper 60s/near 70.
Friday and beyond: Highs look to continue to increase steadily through the weekend under mostly sunny conditions. By Sunday, high temperatures will once again be back into the mid 70s, before another trough/cold front encroaches on the region sometime early next week.
There are some indications (through various Numerical Weather Models) the next trough could be on the strong/potent side next Monday/Tuesday.

October Recap:
October, overall, will go down as a near average to slightly above average month temperature-wise, as departure from average temperatures ranged from 1-3 degrees above normal for the month.
Precipitation is a whole different story. Reagan National Airport set a new monthly record rainfall for the month of October at 9.41 inches, more than 6 inches above normal. With one potent weather system during the 6-8th dumping nearly 8 inches of precip at DC, and almost a foot in isolated locations, one would expect rainfall totals nearing 10 inches for the month.
This data, along with other DC climate resources can be accessed through the National Weather Service.
