Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 346 AM EDT Tue May 28 2024 Valid 12Z Tue May 28 2024 - 12Z Thu May 30 2024 ...Numerous strong to severe thunderstorms and areas of flash flooding likely across portions of northern and central Texas today... ...Unsettled weather with thunderstorms and heavy rain possible over the northern Great Basin/Rockies today before shifting into the northern High Plains on Wednesday... ...Sweltering heat continues across parts of South Texas and southern Florida... The Lone Star State will be the focus for active weather today as strong thunderstorms develop along a southern High Plains dryline and lingering stationary front. Ample atmospheric moisture content and instability will support the likelihood of storms containing significant damaging wind gusts and very large hail. Ongoing thunderstorms along the Red River Valley of the South are expected to continue through the morning hours before numerous additional storms form across western and north-central Texas by the afternoon. Merging cells and clusters of storms are also likely to contain intense rainfall rates capable of triggering several flash floods, particularly for areas just west of Dallas-Fort Worth and north of Austin. The threat of scattered flash flooding and severe thunderstorms includes a much larger region extending from the Texas Panhandle to the western Gulf Coast. For the overnight timeframe, heavy rain and severe weather chances are forecast to gradually decrease and slide eastward within Texas. Residents and visitors are reminded to remain weather aware, have numerous ways to receive warnings and never drive across flooded roadways. A cold front progressing across the Northwest, northern Great Basin, and northern Rockies today will provide enough forcing to produce the potential for scattered severe thunderstorms capable of containing damaging wind gusts for parts of northeast Oregon, northern/central Idaho, and western Montana. A few storms may also produce heavy rain and isolated flash flooding. This area of unsettled weather is expected to swing eastward by midweek and enter the north-central High Plains before an expanding area of storminess returns to the central/southern Plains on Thursday. Elsewhere, cold air advection on the southwestern periphery of an eastern Canada low pressure system will produce scattered areas of showers and storms over the next few days from the Great Lakes and Upper Midwest to the Ohio Valley, Mid-Atlantic, and Northeast. A few storms could contain hail and brief damaging winds today from southern Wisconsin to northern Illinois and northwest Indiana. The heat plaguing much of the Gulf Coast and southern Texas is finally abating, but will linger across parts of southern Texas today with heat indices up to 115 degrees. High temperatures are also expected to remain above average and near daily record highs throughout the central and southern Florida Peninsula over the next few days. Snell Graphics available at
