Forecast: Sunny Sunday, Stormy Monday

By Brian Jackson

Almost perfect late spring weather greets us today. Warm, sunny skies and less humid air prevail for the second half of the weekend. Heat and humidity re-enter the picture on Monday along with the chance for thunderstorms before it clears out again and things really cool off on Tuesday and Wednesday.

Mostly sunny, 83-88. High pressure will build in behind the front that passed through last night providing mostly sunny conditions. Some of you near the Chesapeake Bay may see a some clouds early in the a.m. but it should clear out by noon. Humidity levels will drop leaving us with a very pleasant day. Highs will max out in the mid to upper 80s. Winds will be from the northwest at around 10 mph.

This evening presents a fine way to end the weekend. We'll have clear skies and mild temperatures to enjoy. Lows will drop into the mid 60s. Winds will become from the west southwest at 5 mph.

Confidence: Medium-High

Keep reading for the forecast into early next week.

Warm and humid. Chance of T'storms. Near 90. It's a brief relapse to warm and sticky as heat and moisture return ahead of a strong cold front. Southwest winds tap the humidity and highs will approach 90 again in most areas. Skies will turn mostly cloudy during the afternoon and scattered thunderstorms will likely develop ahead of the cold front. Some storms could be strong to severe.

Overnight, the chance (40%) for thunderstorms continues as the front itself pushes through. Clouds will then decrease behind the front west to east and with skies becoming mostly clear by early morning. Lows will fall to the low to mid 60s.


Tuesday brings a glorious respite from the recent heat and humidity. Skies will become mostly sunny with much cooler and drier conditions as winds blow in from the northwest. Below normal temperatures move in to save all of our air conditioning bills. Highs will top out around 80 degrees. Confidence: Medium-High

Wednesday will be a mostly fine day. Expect partly sunny skies and mild temperatures, with highs again around 80 degrees. It's not out of the question a shower or thunderstorm could develop in the afternoon as a little wave in the atmosphere ripples through the region. Confidence: Medium-High

Can you ballpark how much wind might blow in from the NW on Tuesday? Mostly, I wonder if a small craft advisory is likely for the upper tidal Potomac. If not, I may have to play hooky that day...but I have to dig up other delinquent crew first. :-)

Late yesterday, a debate occurred on this sight regarding whether the NWS or SPC should have outlined a severe watch area within the mid-Atlantic region yesterday afternoon.

Are many in our society finding false security in expecting or believing that any government entity can guarantee protection or security from something as unpredictable as the weather?? These folks at NOAA can only (hopefully) provide a "best guess" depending on the tools at their disposal. The human race has much to learn about the intricacies of our daily weather and climate trends, though many in our society don't understand or care to admit the limits of our knowledge.

This morning at 9:42, the folks at LWX prempted the late morning package with the AFD. It contained the following : Will go west/an incrsgly sunny forecast taftn. May be scattered diurnal cumulus...especially southeast...but not much more. WILL RMV ANY PRECIPITATION FROM FORECAST. Not only do observation not support it...the local WRF runs/the only guidance suggesting it may precipate have backed away from this idea as well.

No chance of rain, with an afternoon forecast of sunny skies with temps. 75-85. Two clusters of showers and thunderstorms developed unexpectedly and moved across the central Shenandoah Valley between 1:30-2:30, giving me a very welcome .51 inch of rainfall. So much for the NWS forecast.

Long-range forecasters seem to be expressing high confidence in the upcoming medium-range forecast which highlights a cooler than normal period for us most of the upcoming week. Highest chance of rain seems to be late tomorrow. There could be more wind shear than we had with yesterday's storms.
