Opressive heat and humidity to deal with today but some relief is on the way so hang in there!

Tuesday: Record Challenging Heat; Humid; Isolated PM Storms

Highs: Upper 90s (Feels Like: 102-108) | Air Quality: Code Orange

Overnight: Isolated Evening Storm; Otherwise Partly Cloudy; Muggy & Mild

Lows: Mid 70s | Wind: N 5-10

Wednesday: Partly Sunny & Hot; Isolated PM Storms

Highs: Low - Mid 90s | Wind: NW 5-10

The heat and humidity will be in full effect today with dew points in the 70s coupled with temperatures shooting into the upper 90s. The result will be a heat index, a feels like factor, that will be between 102-108 degrees by this afternoon. A HEAT ADVISORY will be in place today from noon until 8 PM for Montgomery, Fairfax, Prince William, Southern Fauquier, Culpeper, Orange, and all Counties south and east to the Chesapeake Bay.

A trough continues to linger just east of the Appalachians so I will leave in the mention of a few isolated PM storms especially south and east of D.C. across Southern Maryland. Any thundershowers will dissipate quickly after sunset leaving muggy and mild conditions in their wake.

A cold frontal boundary will push through the region Wednesday before stalling to our south. Again tomorrow with the boundary passing through I can’t remove the chance of a few storms from the forecast but I do feel that any activity would again be quite isolated. Dew points will begin to drop tomorrow behind the front however it will still be a rather hot day with highs in the low to mid 90s.

Thursday and Friday look to be the gems of the week featuring plenty of sunshine, low humidity and highs in the mid to upper 80s. High pressure will shift to our east over the weekend allowing for southerly winds which will lead to a gradual return of humidity and slightly hotter temperatures.
