March to July in 10 Days

May has been a frustrating weather month, holding on to cold temperatures in the Eastern U. S. But we will experience a quick transformation this week as high pressure muscles its way into control of the East. By early next week, the transition to a summer-like Bermuda high and warmth will be complete. Meanwhile however, a warm front just to our south today and Tuesday, produces lots of clouds. This afternoon has scattered PM showers and storms, fewer showers and thundershowers Tuesday afternoon but still in play.

Monday Hi: 59 Lo: 48 Mostly cloudy; Patchy fog near the Blue Ridge; Scattered PM showers & storms; Light wind becoming SE 5-10 mph

Tuesday Hi: 62 Lo: 49 Mostly cloudy with early fog near the Blue Ridge; Scattered PM t-showers; SE wind 5-10 mph

Wednesday Hi: 65 Lo: 48 Mostly to partly cloudy; Cannot completely rule out a afternoon t-shower; Light wind becoming South 5-10 mph

Thursday Hi: 68 Lo: 48 Clear; Warmer

Friday Hi: 71 Lo: 50 Mostly sunny & warm

Further Out

Saturday - Mainly sunny & warm; High in the lower 70s; Low in the lower 50s
Sunday - Partly sunny; Warm; High in the lower 70s; Low in the lower 50s

Forecast Discussion

After an unsettled and cool first half of May, we are on a quick march to summer. Three transition days are in between.

A warm front lies just to our south today and Tuesday. It will keep clouds and PM showers/storms in the region both days, Monday afternoon is more actives than Tuesday. Outdoor plans will be much safer in the morning hours. Both days remain cooler than seasonal averages.

But... high pressure muscles into the Mid-Atlantic beginning Wednesday and spreads to take over the entire Eastern half of the U. S. This weekend, it slides into the Atlantic and early next week assumes the classic position as a Bermuda High.

Changes to our weather will be welcome and pretty dramatic. Clouds decrease late Wednesday (I cannot complexly rule out a stray shower or thundershower). Then skies will be clear by Thursday. Ample sunshine rules the rest of this 7-day forecast. Warmer temperatures come with the transition. Lower valley locations break into the 80s early next week. Summer-like warmth will eventually produce isolated afternoon convection, but I've kept it out of the extended forecast for now.
