Forecast: A Duo of Comfortably Cool Days

By Matt Rogers

* Climate Goals | Later: Around the World of Weather Media *


Today: Mostly sunny, high near 70. Tonight: Mostly clear, cool. 36-46. | Tomorrow: Mostly sunny, again. 70-73. | A Look Ahead


Very low relative humidity, like the kind we will see today into tomorrow, is both a positive and a negative. On the positive side, the lack of humidity will make the near 70-degree temperatures feel very comfortable (although maybe a bit cool at times in the shade). On the negative side, the low humidity means every bit of new pollen will float easily along in the breezes. So gear up on the allergy medication and enjoy the lovely weather. More rains are looming by tomorrow night and more likely now into the weekend too.

Today (Tuesday): Mostly sunny, grade-A day with highs near 70. Thank you Canadian high pressure. Light breezes will blow from the north at 5 to 10 mph. Confidence: High

Tonight: Mostly clear and quite cool actually with lows in the upper half of the 30s in the outer suburbs toward the mid-40s downtown. Confidence: High

Keep reading for the forecast through the weekend...

Tomorrow (Wednesday): Mostly sunny skies again, although clouds may increase by evening. Highs should be a wee bit warmer than yesterday, reaching the lower 70s. Confidence: Medium-High

Tomorrow Night: Showers cannot seem to stay away too long these days and sure enough, we see more opportunities here, especially after midnight (40% chance). Lows in the 50s. Confidence: Low-Medium


Thursday keeps the clouds around, especially in the morning (along with a 30% chance of more showers), but temperatures will continue their climb and reach toward the mid-70s. Confidence: Low-Medium

Friday, Saturday, and Sunday are warmer (that is the good news) with upper 70s and possibly a few lower 80s around the area, BUT, yes there are more chances for showers and thunderstorms again (30% Friday, 40% Saturday, and 70% on Sunday). Look for lows in the upper 50s to low 60s. Confidence: Low-Medium

How's about a preview of the weather for Memorial Day weekend? Please! Accuweather is now worthless. Their forecast accuracy now is worse than Bob Ryan's. TIA

Sorry sheepherder -- Memorial Day weekend is too far away to give you a reliable forecast. We'll give it our first shot this coming Monday.

Any more detail on the t-storms for Sunday? Are they going to be due to a cold front? Afternoon pop-ups?

Yes, Camden, a perfect morning, though a bit on the cool side.

What bugs me is the fact we're still waterlogged, with more rain and raw crud in the near future. This full weekend looks bad with fronts moving across the area then stalling, principally to our southeast. It's not a huge dance weekend, but Memorial Day weekend is, with dance opportunities each evening from Friday, May 22 through Tuesday, May 26...hope the rain dance crowd stays out of the picture that weekend.

At this time the rain itself hasn't been as annoying as the general moisture "funk" pervading the whole region. Drying conditions are atrocious and COULD WELL STAY THAT WAY [!] until hurricane season fades away with the onset of drier weather next October. We are totally waterlogged here in Northern Virginia, with mold & mushrooms starting to pop up around here. A Bermuda High heat wave of 3 or more days would actually be welcome if it improves our drying conditions a bit. We seem to now be getting evening thundershowers even when the weather [e.g. yesterday evening] is supposed to be dry. The anti-Bombo rain dance crowd grossly overdid it this spring!

BTW, Topper Shutt has wall-to-wall CRUD in his extended outlook from Thursday on into next week, with highs in the cruddy sixties from Sunday onward. Not what I really was looking for; this recurring pattern could lead to some significant POTOMAC FLOODING if it keeps up.
