KEY MESSAGES

- A Dense Fog Advisory has been issued for the entire Tri-State area until 18Z.

- Rain showers are favored along and north of Interstate 70 Tuesday.

- Thursday could see some fire weather threat along with the potential for rain/thunderstorms for portions of the area during the evening and overnight.

SHORT TERM /THROUGH WEDNESDAY NIGHT/

Issued at 143 AM MST Tue Mar 3 2026

This morning, an approaching low pressure system from the west is drawing in southeasterly winds. This is promoting efficient moisture advection into the Plains, leading to widespread fog, prompting the issuance of a Dense Fog Advisory. We could also see some drizzle across the area. Thankfully, the moisture advection has pushed dew points into the mid 30s, which will severely limit the potential of temperatures dropping below freezing. Isolated pockets dropping to below freezing are still possible this morning, which could lead to very slick spots. Any potential for icing will end by 16Z, but the dense fog threat could linger until closer to 18Z.

Today, as the low pushes over the High Plains, the surface front will occur around 10-13Z. We are still expecting the mid and upper level fronts to be trailing behind 6-12 hours, leaving the mid layers dry ahead during the day. Behind the surface front, we can expect winds Tuesday to be gusting around 20-30 kts. These winds will bring in some cooler air, and with the long lasting fog and persistent cloud cover, highs today will generally be around 50. Throughout the day, as the 500 mb low gets closer and we remain saturated at the surface, there will be a growing potential for light rain.

The rest of the column looks to saturate in the late afternoon, as the 500 mb low also enters. This will be the start of our better precipitation chances. Best potential for precipitation will be along and north of U.S. 36 between 0-6Z. Rain is still expected to be the primary P-type, but some flurries could mix in closer to 6Z. Precipitation will taper off from west to east between 6-15Z. As a sidenote, there is a 5% chance of a brief thunderstorm around 0Z this afternoon.

Tonight, the low will be exiting, pulling in some weak CAA behind it. This is forecast to allow temperatures to drop to below freezing by morning. There is a 50% chance any remaining liquid on the ground freezes into black ice.

Wednesday looks to be pretty mild as we get a weak ridge to build into the area. This will push out any remaining moisture in the area and allow temperatures to warm back into the mid 60s. Wednesday night could see a return of widespread fog as we get a near repeat of this morning's fog.

LONG TERM /THURSDAY THROUGH MONDAY/

Issued at 310 AM MST Tue Mar 3 2026

Thursday there is a surface low forecast in southwest Colorado and an upper level trough west of the Rocky Mountains. As both traverse eastward towards our region, we are forecast to be under a southwesterly flow. This will further warm conditions with high temperatures forecast in the mid to high 70s.

Southerly winds and a dryline developing in west Texas could allow for further drying to take place lowering relative humidity (RH) values further than currently forecast. RH values are forecast in the low teens for the southwest CWA. A few hours of critical fire weather conditions are possible Thursday afternoon for our Colorado counties. Winds are forecast to pick up Thursday afternoon with gusts up to 35 mph possible. Fire weather concerns will decrease after sundown as RH's and dewpoints are able to recover. Winds will persist through the overnight hours as a deepening upper level trough traverses towards our region placing us in a strong southwest flow under a 250 mb jet streak. This increase in upper level forcing will give us a chance for precipitation overnight Thursday into Friday. Probability of Precipitation (PoPs) range from 20-60% overnight increasing south to north. A majority of the CWA should expect rain as the primary precipitation type based on forecast temperatures above freezing. There is a potential for thunderstorms overnight based on increased MUCAPE over the CWA on the ECMWF and GFS. The ECMWF has it over the entire area while the GFS has it only over the eastern portion.

Friday, our region remains under a strong southwest flow with a deep trough west of the Rocky Mountains. Winds continue to pick up Friday and will reach their peak in the afternoon. A vertically stacked southwest flow will likely allow stronger winds to mix down to the surface Friday afternoon. Winds gusts from 30-40 mph are possible for entire CWA. Winds calm down after sunset returning to our more typical diurnal pattern overnight into Saturday. RH values are forecast in the mid 20s, so fire weather conditions are not a concern at this time. This may chance if we end up not getting much precipitation from Thursday's system.

Our region remains under a strong southwest flow Saturday, so another warming trend is expected. High temperatures for Saturday are forecast in the upper 50s to low 60s. Fire weather could be a concern with RH values forecast in the upper teens for our Colorado counties along with afternoon wind gusts up to 30 mph possible. Low confidence on this currently since RH values will likely change based on how much precipitation we get Thursday though Saturday morning.

Sunday continues to warm with high temperatures forecast in the 60s to 70s. RH values are forecast in the 20s for the CWA. Winds are fairly mild for most of the CWA, but the northwest CWA could see some gusts around 25 mph. Monday continues to be warm with high temperatures in the 70s as our region is under a mostly zonal upper level flow with a low off the coast of Baja California. This system will be something to watch for potential impacts for our area late next week.

AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/

Issued at 409 AM MST Tue Mar 3 2026

Terrible ceilings and visibilities will persist at KGLD until 16-18Z when visibilities improve and then ceilings improve. KMCK has been staying at LIFR conditions most of the night, but we expect times when conditions will shut down the airport. Low level icing is a major threat in these low ceilings. By 20Z, both sites should be back VFR. MVFR to IFR conditions may return tomorrow morning for both sites, higher confidence in KMCK hitting IFR.
