179 AGUS74 KFWR 271546 HMDFWR HYDROMETEOROLOGICAL DISCUSSION NATIONAL WEATHER SERVICE...WEST GULF RFC...FORT WORTH TX 1045 AM CDT MON APR 27 2015 VALID APRIL 27 THROUGH MAY 2 ...MORE RAINFALL IS EXPECTED ACROSS NORTH AND EAST TEXAS THROUGH TOMORROW... ...METEOROLOGICAL DISCUSSION... The upper level storm system responsible for bringing severe weather and heavy rains to portions of the WGRFC area last night, is finally beginning to move eastward. Widespread precipitation amounts of 2-3 inches were observed across the Texas Panhandle, North Texas and East Texas. The highest 24-hour rainfall total of 7.64 inches, was reported near Cleburne, Texas, which is located in Joshua County. Currently, an area of showers and thunderstorms, is moving over portions of the Texas Panhandle and western Oklahoma. This activity is expected to shift towards the south and east through the remainder of the day, as the upper low moves slowly along the Red River. By this evening through the overnight hours, scattered showers and thunderstorms will once again impact portions of North and Northeast Texas, before the upper low finally exits the region. By tomorrow, precipitation is expected to slowly come to an end, as the upper low continues moving eastward. Some wrap-around rainfall is possible across North and East Texas late tomorrow, but no additional significant precipitation is expected after Wednesday. ...PRECIPITATION FORECAST... For Today into Tuesday morning, Mean Areal Precipitation (MAP) amounts of 1.00 to 1.50 inch, are forecast for portions of the Red River and East Texas. Lesser amounts are forecast for portions of North Texas and the upper Texas coast. For Tuesday into Wednesday morning, no significant MAP amounts are forecast for the WGRFC area. For Wednesday into Thursday morning, no significant MAP amounts are forecast for the WGRFC area. For Thursday into Saturday morning, no significant MAP amounts are forecast for the WGRFC area. Moderate or worse drought conditions continue across parts of New Mexico and Texas. In Texas, about a third of the state is experiencing moderate or worse drought (35%), and about 9% has extreme to exceptional drought conditions. In New Mexico, a little over half of the state is experiencing moderate or worse drought (58%). Lake levels in the extreme drought areas of Texas are at or near historical lows for this time of year. Recent precipitation events have brought drought relief to parts of far west Texas, south Texas and roughly the southeast third of the state. The rainfall expected over the next five days over the WGRFC area could produce some runoff over east central and northeast Texas where the heaviest rainfall is forecast. No significant runoff is expected over the remainder of the WGRFC area. ...HYDROLOGIC DISCUSSION... ...Neches Basin... ...Minor Flooding... Heavy rainfall occurred during a brief period this morning in portions of the Neches and Angelina River basins. Releases out of B.A. Steinhagen Lake have increased to 19,500 CFS this morning. Flooding in the Neches and Angelina River Basins is expected to remain in the minor category. ...Remainder of WGRFC Basins... Minor flooding continues in the Brazos, Guadalupe, Neches, Sabine, San Antonio, San Bernard, and Trinity river basins. Moderate flooding is forecasted at a couple of locations in the Trinity and Guadalupe river basins. Rainfall sufficient to cause additional significant flooding is not forecast in the next 5 days. ...SUPPLEMENTARY GRAPHICAL INFORMATION...
