KEY MESSAGES

- Cloudy and cool with widespread showers and thunderstorms eastern mountains and plains today, beneficial rainfall possible over much of the plains. - Drier and warmer most areas Thursday and Friday, though enough moisture lingers for a few afternoon showers and storms both days. - Weekend looks warm and dry as well, as trend toward wetter and cooler conditions has shifted into early next week.

SHORT TERM /THROUGH TONIGHT/

Issued at 1216 AM MDT Wed May 27 2026

Compact upper circulation/low over the wrn TX Panhandle early this morning, with area of showers already pushing northward into sern CO as of 1 am. Expect circulation to continue to drift slowly northward through the morning, with rainfall area expanding into the I-25 corridor by 6 am. Most models then keep rainfall going into the afternoon from the eastern mountains out across the plains, as upper low drifts slowly northward through ern CO during the day. While precip will be mostly steady light/moderate rain this morning, CAMs suggest a slow trend toward more showery precip this afternoon, with a few embedded thunderstorms possible, mainly east of I-25. 27/00z deterministic model QPF amounts are fairly impressive over the area, with half inch amounts widespread generally east of I-25, and some pockets of over an over an inch across Baca/ern Las Animas Counties. Didn't go quite as high as model QPFs with our official precip forecast, splitting the difference between drier WPC numbers and wetter models (and ignored the NBM, which looked too dry). Precip drops off quickly west of I-25, with a spotty tenth or two forecast over most mountains and interior valleys. Might not see much if any convection over the ern San Juans, where mid-levels look to dry out somewhat through the day. Max temps will run very cool with clouds and showers, with most areas in the 60s to lower 70s. Upper low shifts into nern CO overnight, ending most precip by midnight across the area.

LONG TERM /THURSDAY THROUGH TUESDAY/

Issued at 1216 AM MDT Wed May 27 2026

Expect Thursday to be mainly drier and warmer as wly flow aloft brings in drier mid-level air, while subsidence behind departing upper low tends to suppress convection somewhat. Still enough low level moisture in place to generate at least isolated late afternoon convection, with several model solutions suggesting at least a few showers and storms lingering through much of the evening over the ern mountains and plains. Much the same set-up for Fri, with dry mid levels limiting mountain convection, while fairly deep low level moisture over the plains keeps at least a low threat of afternoon/evening storms in the forecast.

Weekend now looks mostly dry and warm, as upper low shifts into the northern Rockies and westerly flow shoves most low/mid level moisture east of Colorado, especially Saturday. Weak cold front may arrive late Sunday, with a renewed surge of upslope winds and moisture bringing back shower and thunderstorm chances to the eastern mountains and plains into early next week, though given the rather erratic extended model performance of late, confidence remains rather low in the timing and coverage of precipitation.

AVIATION /12Z TAFS THROUGH 12Z THURSDAY/

Issued at 540 AM MDT Wed May 27 2026

KPUB and KCOS...Steadier showers will spread in from the south through the morning with cigs lowering into the MVFR category at times, especially at KCOS. Winds will initially be dominated by a southeast direction with -TSRA possible at both terminals in the afternoon as winds back to a more easterly direction. -SHRA will become less persistent after 00z-02z with some breaks in the clouds through the evening, though cigs may lower into the IFR category tonight with the potential for fog, especially at KCOS.

KALS will see VFR cloud cover through the day and evening, with showers more likely to stay to the east of the terminal. East winds will spread into the valley through La Veta Pass bringing some gusts in the 25-30 kt range into KALS during the late afternoon and evening. Winds will become light again towards 06z. -KT
