KEY MESSAGES

Updated at 1156 AM MDT Mon Apr 27 2026

- The weather will be more benign today through Wednesday, as we sit between upper level low pressure passages. Temperatures seasonably warm, conditions continue very dry, winds lighter, but still breezy afternoons.

- Rain chances return for Thursday and Friday, along with temperatures becoming well below the seasonal average.

DISCUSSION

Issued at 1156 AM MDT Mon Apr 27 2026

Yesterday's wind/dust maker (upper level system) has exited the region. However, the aforementioned upper level longwave trough over the Canadian Prairies will rotate a lobe of energy extending southward across western CONUS, that is currently phasing with another upper level system over the Great Basin and Central Rockies regions. This phasing will to overlay the region with a modest upper level jet, along with inducing sub-1000mb lee-side surface low dover SE Colorado and NE New Mexico this afternoon. Thus, breezy conditions will remain over the Borderland Region on today and Tuesday. Winds will be 10-20 mph sustained with gusts to 30-35 mph this afternoon, slightly decreasing in magnitude on Tuesday, but remaining breezy. Temperatures this afternoon and Tuesday will remain at or slightly above the seasonal average for the end of April. On Wednesday, weak/flat upper level ridging will move across the Desert Southwest with fair and quiet weather conditions. Temperatures will remain around average. Surface pressure gradient on Wednesday will relax, thus winds decreasing further in magnitude becoming generally light.

Thereafter, model guidance and their respected ensemble suites are coming more and more into agreement with the next storm system's evolution. Confidence is increasing that anomalous moisture values will advect into the area, increasing precipitation chances Thursday and Friday. However, some of the discrepancies that remain include the timing of said storm system and precipitation amounts. These types of details will get ironed out in the days to come. That said, expect high level clouds to start increasing during the Wednesday timeframe, with probability of precipitation increasing from west to east on Thursday - lasting through Friday. Convective parameters at this moment look sub-par, expect mostly shower/stratiform rain activity through the duration of the storm system. Temperatures as this system pass through will become well below average, with highs on Thursday, Friday, and Saturday 5-12 degrees below the seasonal average.

AVIATION

(18Z TAFS) Issued at 1156 AM MDT Mon Apr 27 2026

VFR conditions expected through the period. Winds will become breezy this afternoon out of the SW/W at 15-18 knots with gusts to 25-28 knots. Winds will slowly decrease after sunset. Skies currently SKC, will become FEW-SCT at 25 kft late this afternoon and evening.

FIRE WEATHER

Issued at 1156 AM MDT Mon Apr 27 2026

Elevated to near-Critical fire weather conditions on today and Tuesday. Min RH values today will drop to critical thresholds both today and Tuesday the teens to low 20s areawide. Persistent troughing over the Great Basin will keep winds breezy/borderline red flag criteria through Tuesday. Winds will be 10-20 mph sustained with gusts to 30 mph. That said, a Red Flag Warning is in effect for the NMZ113. Elevated fire weather conditions will exist elsewhere this afternoon with Elevated conditions areawide on Tuesday.

Thereafter, model guidance and their respected ensemble suites are coming more and more into agreement with the next storm system's evolution. Confidence is increasing that anomalous moisture values will advect into the area, increasing precipitation chances Thursday and Friday.
