Today's Weather Story

Isolated to scattered showers and thunderstorms are expected today through Memorial Day. Today is the best chance for any convection in the valley, while afternoon thunderstorms area expected everyday. The main low pressure area will slide east of the region later today to bring a gradual warming trend through Memorial Day. When thunder roars, go indoors. Just because it’s sunny where you are, doesn’t mean lightning can’t strike.

Heavy rain and potential flooding in the Plains

A slow-moving weather system with abundant moisture will bring heavy rainfall across portions of the Central and Southern Plains Saturday. Soils in the region are already saturated from recent rainfall, so flash flooding and river flooding are likely.

...Heavy rain possible for portions of the Southern/Central Plains and parts of the Central High Plains...

..There is a slight risk of severe thunderstorms for parts of the Southern/Central High Plains...

A storm over the Southern High Plains will slowly move northward to the Central High Plains by Sunday evening. Moisture from the Western Gulf of Mexico will flow northward over the Plains on Saturday and into the Mississippi Valley by Sunday. Showers and thunderstorms will develop over the Southern Plains and expand northward into the Central/Northern Plains by Saturday evening. On Sunday the showers and thunderstorms will expand into parts of the Mississippi Valley. Rain will also develop over parts of the Northern Plains into the Upper Mississippi Valley by Sunday morning. By Sunday evening rain will develop over parts of the Great Lakes.

In addition, the upper-level trough associated with the storm will aid in producing late night/morning rain with embedded thunderstorms over parts of the Northwest/Great Basin into the Northern/Central Rockies through Sunday. Additionally, afternoon and evening showers/thunderstorms will develop over a greater area of the Northwest/Great Basin into the Northern/Central Rockies and the Northern High Plains on Saturday and Sunday.

Elsewhere, showers and thunderstorms will develop along parts of the Central/Eastern Gulf Coast through Sunday. Light rain will develop over parts of Northern New England on Sunday ahead of a front moving over the region.

NOTE: The HPC National Forecast Map above, provides an overview of today’s national weather with an emphasis on certain hazardous and significant weather. It summarizes forecasts from several NCEP Service Centers including the Storm Prediction Center (for severe thunderstorm and tornado outlooks), the National Hurricane Center (for tropical storm and hurricane forecasts), and the Hydrometeorological Prediction Center (for information concerning heavy rainfall, flooding, winter weather, and general weather). With an overlaid frontal forecast, this display serves as a great overview of the weather for the current day! The National Forecast Map is prepared twice daily at the Hydrometeorological Prediction Center.

Weather History for May 24
1894 - Six inches of snow blanketed Kentucky. Just four days earlier as much as ten inches of snow had fallen across Kentucky, Tennessee and Virginia. Six days earlier a violent storm had wrecked nine ships on Lake Michigan. (David Ludlum)

1930 - A tornado touched down near the town of Pratt, KS, and traveled at the incredibly slow speed of just 5 mph. (The Weather Channel)

1940 - Hail fell near Ada OK to a depth of six to eight inches, and rainfall runoff left drifts of hail up to five feet high. (The Weather Channel)

1987 - Severe thunderstorms in southwest Texas spawned a couple of tornadoes near Silverton, and produced golf ball size hail east of the town of Happy. Thunderstorms also produced large hail and damaging winds in Louisiana and Texas. (Storm Data) (The National Weather Summary)

1988 - Thunderstorms produced severe weather in the southeastern U.S. Thunderstorm winds gusted to 88 mph at Columbia, NC. Baseball size hail was reported near Tifton GA. (The National Weather Summary) (Storm Data)

1989 - Thunderstorms developing ahead of a cold front produced severe weather across the Upper Midwest through the day and night. Thunderstorms spawned 30 tornadoes, and there were 158 reports of large hail and damaging winds. A strong (F-3) tornado caused five million dollars damage at Corning, IA, and a powerful (F-4) tornado caused five million dollars damage at Traer, IA. Thunderstorm winds gusting to 88 mph killed one person and injured five others at Stephensville, WI. (The National Weather Summary) (Storm Data)

1990 - Severe thunderstorms spawned two dozen tornadoes from Montana to Oklahoma. Four tornadoes carved a 109-mile path across central Kansas. The third of the four tornadoes blew 88 cars of an 125-car train off the track, stacking them three to four cars high in some cases, and the fourth tornado caused 3.9 million dollars damage. The third tornado injured six persons who were trying to escape in vehicles. A woman was "sucked out" of a truck and said that at one time she was "airborne, trying to run but my feet wouldn't touch the ground". She also saw a live deer "flying through theair". (The National Weather Summary) (Storm Data)
