Weather Summary

Weather Underground Forecast for Thursday, May 23, 2013. A strong, large storm will continue making its way through the eastern third of the country on Thursday, producing more, active weather east of the Mississippi Valley. While the active weather is not likely to produce the severe thunderstorms that have greeted the country over the past several days, scattered thunderstorms will be likely, especially in the Southeast. In addition, moderate to occasionally heavy rain will move through the Northeast, followed by cool showers in the Ohio Valley and Upper Midwest.

Meanwhile, some moisture pushing into the Southern Plains could possibly instigate some severe thunderstorms in northern Texas and western Oklahoma. Due to this possibility, the Storm Prediction Center has issued a slight risk of severe weather in the area for Thursday. This means residents in the area should prepare as if severe weather will develop, making any necessary preparations to protect life and property.

Also, a seasonably strong low pressure system will linger over the Pacific Northwest today, allowing wet weather to continue in the area. While rain will be the overwhelming precipitation due to this storm, a few snow showers will be possible in the higher elevations of the Cascades.

Additionally, rain will also spread as far east as central Montana.

The Northeast will rise into the 70s and 80s, while the Southeast will see temperatures in the 80s and 90s. The Southern Plains will rise into the 80s and 90s, while the Southwest will see similar temperatures.

... Severe weather stats to date..

The severe weather season became much more active in the past ten
days including in parts of the Midwest. Significant tornado
events in Moore Oklahoma on may 20th and in Texas on may 15th
highlighted this active period.

Despite numerous periods of thunderstorms across the NWS Chicago
County Warning Area /cwa/ on may 19th-21st... the number of
reports thus far remains below normal. Across the Chicago
cwa... there have been 25 preliminary reports of severe weather.
This criteria includes hail of diameter one inch or larger... wind
damage... or wind gusts of 58 mph or stronger. Here is a look at
the number of reports vs normal:


All data through may 23rd...
                         2013* 20-year median 5-year median
severe weather reports 25 42 38
tornado reports 0 2 2

* preliminary

In the past decade... only 2010 had started with fewer severe reports
through this time. However... to show how that cannot be taken as a
strong predictor for the rest of the season... June 2010 would see a
considerable increase in severe weather including numerous tornadoes
on June 5th.


For warnings issued by the NWS Chicago office:

All data through may 23rd...
                         2013 20-year median 5-year median*
svr T-storm warnings 20 46 28
tornado warnings 0 5 3

* this period entails storm-based warnings instead of County-based
warnings used prior.


While there are chances of thunderstorms this Holiday weekend into
next week... the overall weather pattern is not as conducive for severe
storms at this past week. But the severe weather season is still
near its peak going into June and tails off slowly through Summer. The
recent severe and tornadic weather across the nation should serve as a
reminder of the importance of preparedness and having a plan of action.
