Texas Climate Report: April 1999
Most of the state experienced slightly above normal temperatures for the month of April. The mean monthly temperatures were barely below normal for El Paso, San Angelo, Lubbock, and Amarillo where departures from normal ranged between -0.1°F and -2.0°F. Areas in the Panhandle and the Low Rolling Plains dealt with way above normal precipitation totals for the whole month. A small area encompassing San Angelo and Del Rio also dealt with above normal precipitation. As far as the rest of Texas was concerned, precipitation was below normal during April.
A front passed through Texas during the first few days of April bringing showers and storms to areas in Central and East Texas. Reports of small hail and wind damage were numerous as the thunderstorms progressed from west to east. Once the system exited to the east clear and warm weather followed for the Lone Star State. Record high minimum temperatures occurred at Houston on the 7th (72°F) and 8th (74°F). Del Rio and Austin also set record high minimum temperatures on the 8th when their respective low temperatures only fell to 70°F and 69°F. On the 11th a record high temperature was set at Galveston with the temperature reading climbing to 82°F.
A slow moving system crossed Texas from the 12th to the 14th. The storms caused winds to gust to 60 mph in Dalhart, TX and 59 mph in Childress, TX. Observations of large hail (baseball) and possible small tornadoes were common in the High Plains and the Low Rolling Plains on the 13th. Nearly an inch of rain was reported at Easterwood Field in College Station on the 14th alone. Much colder temperatures eventually encompassed all of Texas as the low-pressure system entered into Louisiana.
Nearing the end of the month (18th to the 24th) topsoil turned dry again in southern Texas. Storms that originally formed in Southeast Texas late on the 25th eventually stretched into a large squall line as they crossed the state. The squall line affected areas adjacent to the Gulf of Mexico as well as the areas bordering Oklahoma. Once again hail, heavy rains, strong winds and possible tornadoes were reported as the squall line crossed through Texas.
