Our next storm system, that will affect our weather, is currently moving from down from the Pacific northwest. It will move as far south as Nevada before opening up and moving east across the Plains. Ahead of the upper-low, moisture will begin advecting into our area, indicative of the mostly cloudy skies today. Showers and thunderstorms will begin to overspread the area as early as tonight and become widespread on Thursday into Thursday night. There is some marginal instability with this system and very high shear, thus we cannot rule out one or two severe storms with moderately sized hail, but overall widespread severe weather is not expected with this system. However, PWATs are expected to climb to 2 inches by Thursday. This will allow for storms to produce heavy rainfall. So by far our biggest threat with this system will be heavy rainfall. Since our grounds are saturated and cannot hold anymore water, the National Weather Service in Fort Worth has already issued a Flash Flood Watch for nearly the entire forecast area. Widespread 1 to 2 inches look like a good bet with this system with isolated higher amounts.

A cold front will move across the area behind this system early Friday. This front will bring a little chill to the air as it has some Canadian air behind it. Thus, morning low temperatures are likely to dip into the 40s for the first time this year at DFW Airport over the weekend with highs struggling to make it into the 60s on Sunday. The models continue to hang back some energy for the weekend. Thus, after a dry day on Friday, low end POPs are warranted for Friday night into Saturday for some light rain in the cooler air.

We are watching another storm system for early next week that has the potential to bring more showers and thunderstorms to DFW. A stronger cold front may be on tap for later next week.
