A flash flood watch is in effect overnight through 10am morning for the western half of our coverage area. It does not include Dallas or Tarrant counties. You can expect 2″-3″ of rainfall in the watch area with locally heavier amounts:
The DFW airport already logged about a third of an inch of rain by late evening. Just to our north in Wise County one of weather spotters (Donna Giblin in Decatur) reports 1.42″ inches of rain as of 3pm. We are not expecting severe weather overnight but heavy rain and lightning is likely.
Saturday the high at DFW airport hit 101°. At 5pm Sunday it was more almost 30° cooler!
The temperature just after midnight Sunday was 81° which is the official high for the day. That makes it the COOLEST JULY DAY IN SIX YEARS (80° July 5th in 2007).
As much as a shock as the temperature change is the rainfall is the biggest story. We went over three weeks at DFW with only getting a trace of rain. Rain chances stay rather good over the next several days:
Its an usual weather pattern producing all sorts of unusual weather. An upper level low pressure system is moving right over the Red River Valley heading west. Generous rainfall is still to come with the heaviest rain to come overnight.
Even with the low far to the west in New Mexico by Tuesday it’ll draw enough gulf moisture to keep rain chances in the forecast all the way to Wednesday:
This slow moving system and deep moisture will produce generous rains not only in our western counties but also in the drought-stricken areas of west Texas.
The various forecast models continue to show a wide range of rainfall for the next 36 hours:
Most of the models agree that the heaviest rain will fall in the western third of north Texas:
As high pressure moves in from the east coast and into the Ohio Valley it will bring up moisture levels in the atmosphere to the highest it’s been this year! Though rain coverage will lessen as the low moves west heavy rain will continue to be in the forecast.
The clouds will keep temperatures below normal all the way to Friday. Compare this with the 100° highs of all last week!
