.SHORT TERM... (Today and tonight) Issued at 1211 AM CDT Fri Oct 3 2025
Other than today`s forecast highs dialing back a smidge from Thursday`s summerlike readings, the overall quiet and dry theme is stuck on repeat as we remain under a pesky upper ridge. This ridge will at least undergo a slow decay today as it compresses in response to an upper low trekking east from northern California, so we`re looking forward to highs only around 10 degrees above normal instead of nearly 15. Water vapor imagery continues to show a pool of mid-level moisture trapped under the ridge from the TX Panhandle to the South Plains, so we should see another round of high-based afternoon cumulus. Some of these clouds could manage virga or sprinkles across our northwestern counties along a low-level thermal ridge where vertical mixing should be maximized. Otherwise, dry and light southerly flow holds firm through tonight allowing for comfortably cool lows in the 50s on the Caprock.

.LONG TERM... (Saturday through Thursday) Issued at 1211 AM CDT Fri Oct 3 2025
The low/trough discussed in the short term will eject from the Intermountain West, accelerating over the central and northern High Plains as it deamplifies late Saturday. The shortwave will make quick progress through the Upper Midwest, crossing over into south- central Canada by Sunday evening. Increasing southwesterly flow aloft in advance of and during the trough passage to our north will induce falling surface pressure in the lee of the Rockies. The net result locally will be a tightening pressure gradient and modestly breezy winds both Saturday and Sunday. Unfortunately, for those wanting precipitation, rain doesn`t appear to be in the cards as the best lift and deep-layer moisture will stay well north of the region. In the wake of this storm system, a cool surface high will spill out of Canada and into the center of the nation Sunday into Monday. However, flat upper ridging over the Deep South is progged to build westward across Texas early next week, which will tend to impede the southward push of the cooler air. Given this, it is not surprising that the general consensus of the NWP is that the frontal zone will stall out to our north early next week. That could change around the middle of next week as energy pivoting through broad troughing over much of Canada (and skirting the Upper Midwest and the Great Lakes) on Tuesday gives the surface ridge a reinforcing shot. The thrust of the push will be to the east, but we could see cooler air attempt to briefly backdoor into the region. If this happens, temperatures could dip to near or even below average for a day or two. The approach of the frontal zone and an increase in deep- layer moisture will renew rain chances, though the mid-upper ridge isn`t expected to completely yield, which could hamper overall rain chances/coverage. For now, we have accepted the NBM`s slight to chance PoPs, with the greatest coverage and chances centered around late Tuesday and early Wednesday. Aside from the middle of next week, above average temperatures will dominate, though they will back off a bit from what was experienced earlier this week.
