Gray skies and cool air of the morning could not hold back the warmth surge this afternoon, and many places made it up to the mid-60s or around 70 for highs. Really warm air wasn’t too far off either, with a large part of Virginia basking in 80-degree or higher temperatures today. Our proximity to a warm front hanging in the region means we won’t be seeing readings that warm locally in the time ahead.

Through Tonight: Clearer skies of the late day again give way to mostly cloudy conditions. There could be a sprinkle or brief shower after midnight, especially north and northwest of the city. Lows range from the mid-40s to near 50 most spots.

Tomorrow (Thursday): Clouds dominate the day, thanks to a warm front still hanging out in the area and a wave of low pressure riding along it. Morning brings an outside risk of a passing sprinkle or shower, and odds increase to at least 50% of some shower activity by late day or evening. It shouldn’t be an all day thing though, and may focus north. Highs still shoot for the mid-60s (63-67), perhaps even higher if we see more sunshine. Winds are from the east around 5-10 mph.

Bless you: As plants continue to come to life, tree pollen remains high in the area, with 109 grains per cubic meter observed at last count. This is only about 1/3rd the typical level for this time of year, and about 1/10th of the typical peak output. All other pollens remain low still. Make no mistake, a bumpy road lies ahead for allergy sufferers!
