They system of interest we’ve been tracking for last couple of days is now moving into the Southwest. The forecast details on this upper level low remain unchanged. The track is right across Texas and it’s strong enough to produce good dynamics to develop showers and storms.
As this system pushes into Texas, it will also pull moisture in to work with impressive dynamics for rain and storms. Some storms will have high rainfall rates of 2″ – 3″ per hour or even higher in stronger downpour cores. We will also be on the lookout for brief strong gusts especially if the storms form into a complex or line. This mode of thunderstorms typically is a wind risk and lower on the large hail risk.
As for the flooding risk, we’re in a level 1 of 4 flood outlook but the Hill Country is in a level 2 of 4 outlook where probabilities of some flooding are higher.
Storms will develop out west then move into our area late evening to midnight. They’ll move across overnight to Saturday morning then push east. That said, we may see additional pop-up showers or a t-storm develop Saturday into the afternoon. The big system moves away Saturday night to Sunday.
Total rainfall, I expect a .50″ – 1.50″+ rainfall. Our far southern tier counties will see much less unfortunately based on current forecast trends as there will be a sharp drop off with shield of rain and storms.
