Severe Potential Friday, Heavy Rain Saturday
5:00 p.m. Thursday 27 April 2017
Thursday was a beautiful day with sunshine and highs in the 70s, but gusty winds did return this time from the south. The winds remain rather gusty tonight, keeping lows about 20 degrees warmer than last night under partly cloudy skies.
Friday will be a much more humid day than today as a warm front surges northward during the day, highs will hit the low 80s with gusty winds once again at 20 to 30 mph. A few moderate thunderstorms are possible by mid to late afternoon, but my main concern comes a bit later Friday evening. Dry-line thunderstorms forming about 100 miles to the west of I-35 will be capable of producing large hail and tornadoes, if they develop. There will be a fairly stout “cap” in place, so it’s not certain if any storms develop at all, if they do they will likely be severe and move from west to east into Texoma Friday evening/night.
A heavy rainfall event evolves Saturday as the most humid air so far this spring meets up with an approaching front and some lift provided by a slow-moving upper low. A few severe storms will still be possible Saturday, but the biggest weather story on Saturday will be heavy rainfall, three to five inches in some places.
Sunday looks to be mostly cloudy windy and cool behind the front, highs will be around 60. Sunshine returns early next week with warmer temperatures returning to begin the month of May.
Here are the numbers:
Tonight: Partly cloudy, windy, mild…Lows 59-63
Friday: 30% Thunderstorms day, 60% evening/night, some severe…..Highs 78 to 82
Saturday: 90% thunderstorms, heavy rainfall.….70/74
Sunday: 20% Rain a.m., windy and cool…..50/58
Monday: Sunny skies…..46/74
Tuesday: Mostly sunny…..53/78
Wednesday: 40% Thunderstorms…..59/67
Thursday: Mostly sunny, windy 50/68
