A cold front will help set off showers and thunderstorms across Oklahoma, and some of these will work their way south of the Red River late tonight and into Thursday morning. Gusty winds, cloud to ground lightning, and locally heavy rainfall will be the main hazards from any storms. Otherwise, low temperatures will be in the mid 70s to near 80 degrees across the region.
Isolated to scattered thunderstorms will be possible over eastern and northeastern portions of our forecast area this weekend. Highs will be in the mid 90s to near 100 for most areas. Combined with humidity, this will lead to heat index values in excess of 105 in some locations.
A total solar eclipse will occur on August 21, 2017. Unfortunately, North and Central Texas will be well away from the path of totality (where it actually gets dark). Coverage of the sun over North and Central Texas will range from around 69 percent in Brownwood to nearly 82 percent in Texarkana. The moon's shadow will move across the U.S. at over 1500 mph! The transcontinental trip will occur in 90 minutes! The last time that we've been able to view this much of a solar eclipse was on May 10, 1994. The next solar eclipse that will be viewable from Texas will be an annular eclipse on October 14, 2023. During this event, the maximum shadow (~90 percent coverage) will track from Albuquerque, NM to San Antonio to Corpus Christi. A Total Eclipse will occur on April 8, 2024. Totality will occur from Del Rio, to Killeen, to Dallas, to Little Rock, AR.
Each late night and morning, weakening storm complexes will move across the Red River and especially across the northeast counties and areas north of I-20/30. Brief heavier downpours will be possible each day, but widespread heavy rainfall is NOT expected. Localized minor flooding may occur across areas in the northeast parts of the area that saw heavy rainfall the previous weekend.

September 2010 Review

Tropical Storm Hermine brought a deluge to the I-35 corridor, with widespread storm totals in excess of 5 inches.  Over 10 inches fell in south Arlington, resulting in high water rescues.  A life was lost in Johnson County as a result of the flooding.  Another flood death occurred in Bell County where many areas saw more than 10 inches of rain.

In addition to the torrential rains, Hermine spawned several tornadoes across North Texas.  The strongest was rated EF-2, impacting west Dallas near the intersection of Mockingbird Lane and Irving Blvd. The tornado caused minor roof damage to several buildings and caused extensive damage to a warehouse.
