Weather Summary

Weather Underground Forecast for Thursday, May 24, 2012.

Rain and thunderstorms will continue across parts of the Midwest and Central Plains on Thursday as low pressure forms along a cold front extending through the Central U.S. The heaviest amounts of rain are anticipated near the front in areas of northern Wisconsin, southern Minnesota and Iowa. There is a slight risk of severe storms for the Upper and Mid-Mississippi Valleys Thursday afternoon and night with damaging wind gusts and isolated tornadoes.

In the West, a strong storm system will drop southward from the Gulf of Alaska on Thursday. This system will lead to an increase in showers and possible thunderstorms across the Pacific Northwest and Northern Intermountain West. The colder airmass accompanying this system will lower snow levels in the mountains and cause temperatures to run about 10 degrees below normal for this time of year. Meanwhile, winds will pick up across the rest of the West, increasing fire danger potential across the Southwest and parts of southeastern Utah and southwestern Colorado.

In the East, light showers and afternoon thunderstorms will remain possible across the Northeast and Mid-Atlantic states. To the south, heavy rain and strong thunderstorms with gusty winds are expected to continue across the southern tip of Florida. Saturated grounds from heavy rainfall that occurred during the last couple of days combined with Thursday\'s rainfall will continue flood concerns near Miami-Dade County.

Special Statement
Mobile & Email Alerts Statement as of 3:45 AM PDT on May 24, 2012

... Cooler and unsettled weather Friday...

A cold late-season weather system will drop southward through
northern California on Friday before moving east on Saturday.
Showers and a few thunderstorms are expected to spread southward
through the region early Friday and begin to taper off late
Friday... however lingering showers along the Sierra are expected
into Saturday.

Locally gusty winds with brief heavy showers are possible during
thunderstorm development. Light to several inches of snowfall
could accumulate along the higher elevations of the northern
Sierra crest... generally above 5500 feet. Most roadways will
not see as much snow accumulation due to the warm surface temps we
have been having and longer daylight hours. The system will also
bring much cooler temperatures that measure about 15 degrees below
normal. Campers... hikers and other outdoor enthusiasts are advised
to be prepared for this dramatic change in the weather for the
northern Sierra.
