Grayson County and the Texoma region are expected to receive some much-needed rain Tuesday according to forecasts developed by the National Weather Service.
Meteorologists with the Weather Service’s Fort Worth office said the Sherman-Denison area is almost guaranteed to see showers as the region struggles under an ongoing drought.
“It looks like the chances for rain are probably going to increase into the late morning hours and then it lingers throughout the rest of the day,” National Weather Service Meteorologist Juan Hernandez said Monday. “It doesn’t look like there will be any severe weather, but there will be some thunderstorms and we could see quite a bit of heavy rain if one of the stronger storms manages to pass over the area. We could possibly see an inch to an inch and a half or so.”
Hernandez said the expected rainfall is part of a low-pressure system making its way east across much of the United States. But with the Sherman-Denison area reporting its December rainfalls totals at just more than half an inch, Tuesday’s rains are not expected to get the cities anywhere close to their usual monthly average of 3.14 inches.
“And that’s the case for basically all of North and Central Texas,” Hernandez said. “Rainfall has been hard to come by this fall, but hopefully we’ll get some good numbers in the weeks to come.”
The meteorologist said the persistent dry conditions seen in Texoma are largely the result of stable, high-pressure systems lingering over the area. But Hernandez added that the longer such systems hang around, the more difficult it becomes for rain to form.
“There is an effect there,” Hernandez said. “The dryer it is, the harder it gets for moisture to move into the area. So over the course of months of dry weather, it becomes harder and harder for moisture to settle in and develop into rain.”
With the Texas Water Development Board reporting 37 percent of the state under drought conditions, many counties have been keeping a close eye the need to call a burn ban. Cooke County called a burn ban on Dec. 7 and Grayson County Judge Bill Magers issued a disaster declaration on Dec. 15 so that outdoor burning would cease until county commissioners could discuss issuing a ban this week.
Hernandez said while Tuesday marks Grayson County’s best chance for rain, precipitation could return to the area late Thursday night and late Friday.
High temperatures are expected to remain in the mid 50s Tuesday before dropping to a low of 49 degrees. Following Tuesday’s front, skies are expected to clear and temperatures to rise with highs and lows reaching 66 degrees and 48 degrees respectively on Wednesday and 72 degrees and 40 degrees on Thursday.
Precipitation chances stand at 20 percent on Thursday night and 30 percent late Friday. The predicted high temperature for Friday is just 52 degrees and the low is expected to dip to 28 degrees. With high temperatures climbing only into the 40s on Saturday and Sunday, there remains a slim possibility for snow flurries each day.
