Thunder Threat, Some Drought Denting and More Heavy Rain Potential

Thursday, September 27th, 2012

Thanks to Mike Hall Photography for the picture below from the Hancock County Airport in KY. Several rounds of showers and storms have rolled through the area since Tuesday, allowing for some nice photo ops! Great shot Mike!!

Mike says: “In my top 5 lightning shots of all time. I’m sharing this one everywhere. Taken at the Hancock County, KY airport around 8pm tonight.

Severe Threat Today

The Storm Prediction Center has issued a SLIGHT RISK of severe weather for areas in yellow below. The stalled frontal boundary along with impulses of energy along that front will allow a few strong to severe storms to pop-up. The best chance for hail, high winds and heavy rain will be in those areas. Even though the tornado threat remains low, an isolated tornado can’t be ruled out.

Much Needed Rainfall

Thanks to the slow moving/nearly stalled front across the Ohio River Valley, we’ve seen some much needed rainfall in number of areas from the Front Range of the Rockies to the Northeast. Radar estimates of rainfall suggest a few pockets of 6″ or more, but there have been widespread 1″ to 3″ amounts as well!

Heavy September Rainfall

I thought this was interesting… take a look at the last 30 day radar estimates of rainfall across the nation. Note the heavier totals from the Mississippi River Valley on east! Most of the moisture there is from Isaac that rolled into these areas over the Labor Day Weekend. After a fairly dry and quiet summer, September rainfall totals really ramped up!

Any Rain Helps!

The rains over the past few days won’t be drought busting rains, but there sure are drought denting in a few spots! The latest U.S. Drought Monitor (updated on the 25th and released on the 27th) doesn’t encompass the latest rainfall this week. We will likely wait until next week’s release to see exactly how this and additional rainfall helps the current drought situation.

Weekly Summary: A series of upper-air troughs and accompanying strong cold fronts moved across the eastern half of the contiguous United States during the past week. The East Coast states, and both the Great Lakes region and Ohio Valley, received beneficial rainfall with the passage of these cold fronts. The West was mostly warm (generally 3-7 degrees above average) and dry, and the monsoonal showers and thunderstorms that occurred 2-3 weeks ago shut down this past week over the Southwest. Temperatures in the eastern half of the country ranged from 4-12 degrees below normal, with the core of the coolest air centered over the central Corn Belt.

Additional Rainfall

Nice to see additional heavy rainfall potential in spots that need the rain! Wish we could get more in a number of other locations, but such is life… The image below suggests the rainfall potential over the next 5 days. Note the heavier precipitation across Texas and the Lower Mississippi Valley as the slow moving front slides southeast. Parts of the Northeast will also get a decent shot at accumulating precipitation. Some spots could get 1″ to 2″.

Drought Outlook

NOAA’s Climate Prediction Center has the latest drought outlook, which doesn’t look all that promising. In fact, much of the nation could experience a persistent drought with a chance of above average temperatures through the next 1 to 3 months.

Thanks for checking in and have a great rest of you week!
