PM Update: After sun’s rare appearance, a shower and storm risk

Following what might be the sunniest day area wide in about two weeks, we’re waiting on any showers and t’storms that might cap the day. While sun can help destabilize the atmosphere, we also need an atmospheric “trigger” to fire up storms and so far it seems there is no large-scale one. Temperatures responded to the sun by reaching highs near and above 80 most spots.

Through Tonight: We’ll be watching for isolated to scattered showers and storms (50% chance) into the evening. One or two could turn severe, and even an isolated tornado can’t be ruled out. However, coverage appears minimal thus far and the ingredients, while available, are not great -- if you like lots of storms that is. Still, watch out for heavy rain in anything that forms. Lows should ultimately reach the mid-to-upper 60s. Cheer up though; this might be our last truly muggy night!

Tomorrow (Thursday): We should see some breaks in the clouds again. There’s a slight risk of showers early and that risk builds toward a 50% chance by afternoon as a cold front -- the first one on its way -- moves through. Afternoon highs should head for the mid-70s to near 80, which may be enough heating to turn a few p.m. storms severe.

Predicting a cold: Occasionally, the weatherman likes to step outside his expertise... just tune into the national media after a major earthquake. Now, word comes from South Korea that the Korea Meteorological Administration (KMA) will issue forecasts for the likelihood of catching a cold. Ok, ok, it’s not all a joke… There is some known correlation between dry air, lingering viruses, and such. The KMA will issue these forecasts from November through February. Maybe CWG should have a daily sniffle index?

Pollen update: Mold spores are HIGH, other pollen types LOW.
