PM Update: More pleasant times to come, along with a slight rain risk

Our cooler than average start to June brought us another pretty fantastic one today. Highs reaching into the low and mid 70s, off lows in the 50s, are really quite a treat. We’ve still got some of that cold air aloft helping to create clouds as well, but they’ve generally been fewer than yesterday. The outside risk of a quick shower or t’shower prior to sunset remains low enough to not cause any widespread worries.

Through Tonight: If a shower or t’shower passes by, you may pick up some quick moderate to heavy rain, but it probably won’t last long. Many or most won’t see any rain. Otherwise, clouds decrease with the loss of daytime warmth, leaving us partly to mostly clear overnight. Lows are a touch milder than this morning, but still pretty exhilarating for early June, as they reach the mid-50s to near 60.

Tomorrow (Thursday): The persistent upper-level system associated with the cooler air over the area weakens its grip a bit further tomorrow. That means a little in the way of warmer temperatures and a day likely to see more sun than clouds. Highs in the upper 70s to low 80s may promote afternoon showers or thundershowers, though the risk is not much higher than 30-40%.

Toasty spring: A few days of cool around here is big news of late. Perhaps because we’ve been on quite the warmth roll recently. Spring (Mar, Apr, May) 2012 was no different. NWS Baltimore/Washington announced that the 57 calendar days at or above 70 set a record for the period, besting 55 in 1977. Additionally, the six days below 40 was the fewest on record, with the previous low coming in at 12 in 2010.

Pollen update: Susan Kosisky, of the US Army Centralized Allergen Extract Lab, reports: “Tree pollen is LOW at 1.6 grains/cubic meter. Grass pollen is LOW at 1.92 grains/cubic meter. Weed pollen is LOW at 1.92 grains/cubic meter. Mold spores are LOW at 3529.82 spores/cubic meter.”
