PM Update: Severe storms possible into evening

7:00 p.m. update: The severe storm warning of earlier was canceled early as the storm pretty much fell apart. While the threat for more may not be 0%, the chances of severe weather seem to be rapidly dropping. Still, keep an eye on the sky and prepare for a brief shower or storm should one pop up. We’ll update again as necessary.

6:25 p.m. update: The storm that was warned earlier has been re-warned. A Severe Thunderstorm Warning is up until 7:00 p.m. for Montgomery, Howard and Prince Georges counties. Winds in excess of 60 mph and hail to the size of quarters may be possible in these areas.

Through Tonight: Showers and storms gathering to our west should move into the area just in time for the evening commute. Western ‘burbs face the risk first, where activity may move in within the next hour. The broken line of storms should move toward D.C. by 6 p.m. or so, then head east as we head toward sunset. Though these storms may remain hit-or-miss, they could pack a punch where they hit. Watch out for brief heavy rain and lightning, some isolated wind damage and perhaps even a quick tornado. After the storms pass, the night should be quieter, though isolated additional showers and storms will be possible late as lows reach the mid-60s most spots.

Tomorrow (Tuesday): A weak cold front heads toward the area before stalling out. After some morning sun, this should promote more in the way of bubbling clouds and afternoon/evening shower and t’storm threats once again. Before any rain enters the picture, highs should reach the mid-80s, perhaps warmer depending on timing of clouds/showers. Any t’storms during the late day may be severe with high winds and hail likely to be the main risks. Also, don’t get too excited about the cold front bringing much cooler air, as it looks like more of the same to follow.

Tornado outbreak tomorrow? In addition to yesterday’s tragic tornado outbreak in the Midwest, and odds for more today, the Storm Prediction Center is outlooking a potentially major tornado outbreak tomorrow in the Plains. The main targets for now appear to be Oklahoma and Kansas, where strong long-tracked tornadoes are possible.

Pollen update: Trees are MODERATE (64.86 grains/cubic meter), grasses are HIGH, weeds are MODERATE, and mold spores are MODERATE.

6:05 p.m. update: While no warnings are currently active in the area, and storms are rather isolated to scattered, the risk for severe weather continues (particularly to the east of current activity draped through Montgomery County and southwest/northeast). Due to the continued threat, the National Weather Service has extended the thunderstorm watch until 8 p.m. for portions of the area. We’ll keep you posted should anything else turn severe.

5:15 p.m. update: Storms moving east have prompted a new Severe Thunderstorm Warning for Frederick, Montgomery and Loudoun counties until 6:00 p.m. Hail up to the size of quarters and winds in excess of 60 mph are possible.

4:25 p.m. update:A Severe Thunderstorm Warning has been issued for northern Loudoun County and surrounding areas. This storm is capable of producing winds to around 60 mph as well as hail to the size of quarters and it moving east at 25 mph.

3:30: It’s feeling a bit summerlike out there today with dew points moving on up into uncomfortable levels in the upper 60s. Thankfully, we’ve seen enough clouds to keep temperatures from really soaring – but mid-80s is still warmer than normal and feels pretty hot especially in direct sun. All these ingredients have combined to create a severe weather risk that stays with us into the evening. The main threats with these scattered storms should be high winds, but a brief tornado can’t be ruled out, and the same goes with hail.
