DISCUSSION

Issued at 957 PM MDT Thu Jun 4 2026

Upper low over the central Gulf of California continues to slowly drift northeast pulling up a fair amount of sub-tropical moisture with it. Models show the low between El Paso and the Big Bend Friday afternoon, so expect another round of thunderstorms. MCV, which was over the eastern CWA this afternoon, likely caused some subsidence to its lee over much of the central CWA. This feature should be well out of the area Friday, with the upper low now the main driver. Models showing modest CAPE values of 500-1000 J/kg and PWs of .75 to 1.00 inch well aid in thunderstorm development Friday, with areas from the Rio Grande Valley east with the highest chances. DCAPEs as high as 1000 J/kg and dewpoint depressions of 40-50 degrees point towards winds being the biggest threat, but flooding and hail will also likely be present. Saturday should see less storm activity as the upper low drifts over the Texas Panhandle. Thunderstorms mainly limited to areas east of the Rio Grande Valley as this is the last holdout for moisture and instability.

Sunday through Tuesday...upper ridge builds in over the area behind the exiting upper low. Low level warmth increases and 850 mb temps support lowland triple digits, if not by Sunday, then Monday and Tuesday.

Wednesday and Thursday...Next Pacific system begins moving onshore, displacing the upper ridge further east. Though both GFS/ECMWF show increasing southerly flow tapping into sub-tropical moisture and moving it to our area, the GFS digs the Pacific low much further south (to near the Four Corners Wednesday) and hence much deeper moisture/higher PWs. Thus, GFS Wednesday shows likely thunderstorms, while ECMWF Wednesday just rates a slight chance. The tables flip Thursday as the southerly GFS low passes by, bringing in drier west flow. The ECMWF on Thursday still shows sub- tropical moisture tap since the upper winds remain more southerly. Hence the ECMWF shows the chances of thunderstorms for Thursday.

FIRE WEATHER

Issued at 1104 AM MDT Thu Jun 4 2026

A couple more days of shower and thunderstorm chances as a slow moving upper low/trough linger over the region. This afternoon and evening look like a more down day before ramping up again Friday. Locally heavy rain and flooding will be the main impacts. Saturday storms will remain over the Sacs. As we go into next week, an upper high will be building in and temperatures will reach the warmest of the year with 100+ degree highs on the lowlands. RH's will be falling into the teens by Sunday and remain there into midweek. Winds will remain under 15 mph except near thunderstorm outflows through the period.
