10:00 p.m. update: A convective complex with showers and thunderstorms over Ohio and western West Virginia may hold together and bring showers and thunderstorms to the region very late tonight into tomorrow morning (between about 3 and 8 a.m.). I’ve added this into the forecast below. - Jason
How did you like our warmest day since April 16? Today’s high climbed to 84 - the average high on June 15. After a muggy overnight, we’re right back in the same temperature territory Wednesday. Showers and thunderstorms enter the picture late tonight into Wednesday, a couple of which may be strong.
Through Tonight: Radar is clear and there are no weather worries through this evening. Some of you may mull turning on the A/C, with lows only dipping into the mid-60s downtown, with more comfortable upper 50s in the cooler suburbs. Skies are partly to mostly cloudy, with light winds. Very late at night towards morning, there’s a 50-60 percent chance of showers and storms.
Wednesday: There’s a 30-40 percent chance of morning showers and even the rumble of thunder. Then, partly sunny skies, a touch of humidity and plenty of warmth. There’s not much steering flow with light winds, but an early season heat dome over the region helps high temperatures reach the low 80s. During the afternoon and evening, cumulus clouds build and a few showers and thunderstorms may develop. A few of the storms may produce dangerous lightning and strong, gusty winds. Chance of rain is 40 percent.
Pollen: Trees are MODERATE at 66 grains per cubic meter. Grasses are HIGH for our area at 6 grains per cubic meter. Tree pollen peaked well ahead of normal this year. In most years, it would be peaking right now. Graph showing tree pollen this year compared to the long-term average.
