Additional isolated-scattered thunderstorm development possible this afternoon and evening as a cold front approaches. Main threats will be downburst winds in excess of 60 MPH and hail to 1" in diameter. Storms will move very slowly south-southwestward at around 10 mph.
A Heat Advisory is in effect from Noon through 7 PM today for much of North and Central Texas. The heat and humidity will combine to make it feell like it is 105 to 110 degrees. Take extra precautions if working or spending time outdoors. Take extra precautions if you work or spend time outside. When possible...reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing when possible and drink plenty of water. Check on persons with health problems and the elderly as they are the most susceptible to heat exhaustion and heat stroke.
Isolated to perhaps scattered thunderstorms are possible this afternoon and evening ahead of a southward moving cold front. These storms will have the potential to be severe, producing damaging wind gusts and hail to near 1" in diameter.
More widespread thunderstorms are expected to develop overnight as a disturbance approaches from the northwest. While some of these storms may be strong, producing wind gusts and small hail, they should gradually begin to weaken through the overnight hours. The main threats will gradually shift to a heavy rain threat with localized flash flooding possible.
Waco may reach 100 degrees for the first time this year today. Here are some interesting 100 degree day information for Waco. * The average first 100 degree day is July 4th. * The average last 100 degree day is August 29th. * The earliest occurrence of 100 degrees was March 28th, back in 1971. * The latest occurrence of 100 degrees was October 4th, back in 1983. * We average 24 days with highs of 100 degrees or higher.
Good news! Thanks to a summer cold front that will sweep through North and Central Texas later tonight, a break from the summer heat is expected the next couple of days. Temperatures will be below seasonal normals. Forecast high temperatures will stay mostly in the 80s Saturday through Tuesday, then, warming up to the 90s by the end of next week.
Scattered showers and storms are expected through the morning hours, shifting south by the afternoon. In the morning hours, heavy rain, gusty winds and small hail are possible. As these storms move south, gusty winds and locally heavy rain are the main threats. All showers and storms will be capable of heavy rainfall, which may lead to localized flooding on Saturday.

Historic Texas Snowstorm
December 20-21, 1929

 

 

The first half of December 1929 was remarkably warm across North Texas, most days featuring highs in the 60s and 70s.  However, the mild weather came to an abrupt end on December 17 when an arctic front blew through the region.  Within 24 hours, temperatures had fallen some 40 degrees.  The mercury struggled to top the freezing mark on December 18 despite abundant sunshine.  In the Panhandle, where temperatures were plunging to near 0°F, a strong storm system was invading.  By the morning of December 19, 1 to 2 inches of snow had fallen across portions of the Panhandle.

The system dug slowly southeastward.  Snow began falling in western portions of North Texas during the afternoon hours of December 20.  Lightning and thunder accompanied the snow throughout the following night.  By daybreak on December 21, several inches of snow had fallen across Central Texas from Junction to Lampasas, northeastward to Palestine and Athens.  Clifton and Hillsboro had already accumulated 16 inches of snow by daylight that morning.  The heavy snow continued through much of the day, before tapering off during the late afternoon and evening hours.  By late evening on December 21, the snow was confined to far East Texas.

 

December 1929 Snowstorm - Monthly Weather Review

Monthly Weather Review, March 1930

 

 

The storm lasted barely 24 hours, but the storm totals were nothing short of extraordinary.  A swath of snowfall in excess of 12 inches was 2 to 3 counties wide.  Along the axis of maximum depth, totals exceeded 24 inches, on par with the heaviest snowfalls in Texas history.  Clifton recorded 24 inches of snow in just 24 hours.  Nearby Hillsboro tallied 26 inches.

Where the snowfall was greatest, temperatures plummeted into the single digits.  In Waco, where the 13-inch total remains a 24-hour record for the site, the mercury fell to 2°F, one of the coldest temperatures ever recorded there.  With 2 feet of snow on the ground, Clifton fell to 0°F.  In Dallas/Fort Worth, where only a dusting of snow was recorded during the event., temperatures quickly rebounded, reaching 70°F on Christmas Day.
