Marine Weather and Tide Forecast for La Union, NM

DISCUSSION
Issued at 1030 PM MDT Sat Mar 21 2026

Upper level high pressure is the name of the game on Sunday and through out much of the coming week. We set another daily and monthly record high temperature on Saturday and we could set both again on Sunday as a large upper ridge continues to dominate our weather. Late Sunday night and into early Monday a back door cold front will slip across the region. While we will see some cooling behind the front (5 to 10 degrees), it is possible that El Paso will set another record high temperature on Monday as well. Let that sink in. Behind a cold front with 5 to 10 degrees of cooling we will still be near or even exceed record high temperatures.

The ridge aloft, which had weakened a bit on Monday, roars back to life and will remain anchored across the desert southwest through the end of the week. We will continue to see daily record and possibly even more monthly record high temperatures set on Wednesday and Thursday. By Friday the ridge will begin to weaken and we will see another back door cold front move across the region. This front will "cool" temperatures back down to only 4 to 8 degrees above average for next weekend.

AVIATION
(12Z TAFS)
Issued at 445 AM MDT Sun Mar 22 2026

The large dome of high pressure that has kept VFR conditions over the region, remains locked overhead, despite some weakening, due to minor disturbances passing to our north. For this TAF cycle, that means we will see the reintroduction of some high thin clouds, moving in from the north. Thus, skies will start out SKC, and become SCT250. Winds will be up a bit, after light and variable conditions through the morning. This afternoon, expect winds to be generally W to NW in the 7-12kt range, with some gusts to 22kts. Wind speeds will diminish just after sunset.

FIRE WEATHER
Issued at 445 AM MDT Sun Mar 22 2026

High pressure aloft, still controlling our weather, and keeping the region very warm and critically dry. The upper ridge will flatten today, as a shortwave trough/disturbance passes well to our north. However, this will allow for some moderately breezy afternoon conditions, which will make for ELEVATED fire weather conditions this afternoon. The combination of record warmth, single-digit RH, and breezy conditions will fall short of Critical conditions and Red Flag Warning criteria. Still, the weather and dry fuels will make for increased fire danger.

Again, we remind you that these temperatures are well above normal temperatures, and breaking daily and monthly records for March. A critically dry airmass will mean that minRh will again fall into the single-digits for most locations, with very poor overnight and morning recovery. Fuels will continue to dry, with ERCs back above the 90th percentile.

Monday, a back door cool front, swings in from the NE. We will see a minor drop in temperatures and minor gains in humidity. The improvement is slight and insignificant, with both still excessive for the time of year. Quickly, the ridge rebounds Tuesday through Friday right back to the higher temperatures and lower RH. Fortunately no significant winds are expected with this.

Forecast weather models show NO HOPE of any precipitation through the end of next week.
