NWS Pueblo, CO wrote its last area forecast discussion before this fire weather watch went out at Apr 5, 11:36 PM MDT, 4 hours 45 minutes earlier.
Area forecast discussion, Apr 5, 11:36 PM MDT, 4 hours 45 minutes before
Area Forecast Discussion National Weather Service Pueblo CO 1136 PM MDT Mon Apr 5 2021 .SHORT TERM...(This evening through Tuesday) Issued at 355 PM MDT Mon Apr 5 2021 ...Critical Fire Weather conditions expected across southern CO on Tuesday... Upper low across OR/ID will drop southeastward across CO tomorrow with EC and GFS in better agreement with the upper low centered over north central CO by 00z Wed. Winds have increased across southern CO today ahead of the system with critical fire weather conditions spreading into the San Luis Valley and I-25 corridor this afternoon. Expanded the Red Flags to include southern El Paso county earlier today which appears to be working out. Still monitoring LHX but so far haven't seen gusts strong enough to warrant any further expansions to the east. As for records, have broken the record high at KCOS hitting 79 degrees (old record 77 in 1991). Have tied the PUB record so far of 86 in 1991. KALS still has a few degrees to go to break the old record of 73 in 1943. Clouds may be hindering heating some across the valley but with a few hours to go and some clearing moving in from the west, there is still some time for a tie. Winds across the plains will decrease this evening but humidity recoveries will be poor as enhanced westerly winds into lee side surface low will keep temperatures on the warm side. Winds increase again early Tuesday as the storm system approaches. This combined with the poor humidity recover will result in critical fire weather conditions being met early in the morning across southern areas, as soon as winds increase. There are still some challenges with the cold front timing across the plains with models suggesting the front may push into northern El Paso county and Kiowa county before stalling then getting a secondary push in the late afternoon/early evening as surface pressure gradient tightens and winds become convectively enhanced along the cold front. Could see some spotty high wind criteria in the late afternoon across the plains, though high res models are rather spotty with this depiction and too localized. This may be better handled with convective warnings if needed. Another concern will be blowing dust. Most likely areas for this to occur will be across the San Luis Valley and southern plains along and south of highway 50. Gusts in the afternoon up to 45 mph will be possible with a sudden wind shift in the late afternoon and evening where gusts to around 50 to even 60 mph will be possible. Will have to watch how this evolves as blowing dust warnings may be needed if visibility gets reduced sufficiently. And finally, some snow will spread into the Continental Divide and northern El Paso county during the late afternoon along and behind the cold front. This will be a convective snow NAM showing a few hundred J/kg of CAPE along and behind the front. Could see a rumble of thunder as well, and again this could help mix strong winds aloft to the surface with some localized high wind gusts. Snow will be brief, but could see a quick inch or two of slush on the grass and colder surfaces in northern El Paso county. Given the residual warmth in the ground, not expecting impacts to travel. But visibility could be reduced significantly at times which would be the primary hazard. Overall a very active day in store with weather running the gamut of strong winds, high fire danger, thunderstorms across northern portions of the southeast plains, and even some snow. Please monitor the latest forecasts for possible changes. -KT .LONG TERM...(Tuesday night through Monday) Issued at 355 PM MDT Mon Apr 5 2021 ...Strong Cold Front Tuesday night with Rain and Snow Showers... Tuesday night-Wednesday...Latest model guidance continues to come into better agreement of a compact upper low translating across south central Colorado and into east central Colorado late Tuesday afternoon, with said upper low moving into west central Kansas Tuesday night and into eastern Kansas through the day Wednesday. The movement of this system and its associated surface low sends a strong cold front across eastern Colorado later Tuesday afternoon and evening, with gusty north to northwest winds of 25 to 45 mph in its wake. Latest models also indicate a small ribbon of cape (ml cape around 300 J) along this boundary, leading to the potential for scattered showers and a few thunderstorms across the plains Tuesday afternoon and evening. While convection does not look to be widespread, there will be the potential for localized high wind criteria (gusts >=58 mph) across the plains with progged downdraft capes of 500-1000 J/KG). There is also the potential for some wet snow, especially along the Palmer Divide Tuesday evening, with accumulations of slushy inch or two, mainly on grassy/elevated surfaces. However, with how warm it has been over the past few days, do not believe there will be too many impacts from the snow. Gusty northwest winds, strongest across the eastern plains, as well as dry subsident air across the area on Wednesday, could once again lead to critical fire weather conditions Wednesday afternoon. The areas of highest fire danger will be across the high mountain valleys and into portions of the I-25 Corridor, however, will not issue any fire weather watches at this time. As for temperatures, Tuesday night lows look to be in the 20s and 30s areawide, coldest across the higher terrain, with Wednesday high temperatures mainly in the 60s to lower 70s across the lower elevations and in the 40s and 50s across the higher terrain. Wednesday night-Friday...Moderating west to northwest flow aloft across the area through Thursday increases again Thursday night and Friday, as an upper trough translates across the Northern Rockies and into the High Plains. Models differ on the location of this system, with the EC a tad further south than the GFS, sending a stronger front across the area on Friday. For now, stayed with the blended model solution of dry and warm weather across the area on Thursday, with highs in the 70s across the lower elevations on Thursday, and in the 50s and 60s across the higher terrain. Temperatures cool some 5 to 15 degrees on Friday behind the passing system, with the most notable cooling across the plains, along with a few possible showers over the higher terrain. Saturday-Monday...Dry and warmer weather across the area on Saturday gives way to slightly cooler and more unsettled weather on Sunday, as another upper trough moves across the northern Rockies. Models continue to differ on the location and strength of this system on Sunday, which leads to more uncertainty in the weather into early next week, as a broad upper trough takes shape across the Great Basin. && .AVIATION...(For the 06Z TAFS through 06Z Tuesday night) Issued at 1122 PM MDT Mon Apr 5 2021 At KCOS, VFR the next 24 hrs.

Westerly winds will gust in excess of 40 mph, with some areas gusting in excess of 50 mph. This will combine with humidity values well under 15 percent to produce extreme fire weather conditions. Please do not burn on Tuesday. In addition to the fire weather concerns, the gusty winds will likely produce areas of blowing dust, which could produce hazardous travel conditions across the region due to reduced visibilities. One or two thunderstorms may be possible late this afternoon from the Palmer Divide and areas north of Highway 50. Light snow may be possible on the Palmer Divide and Teller County. Up to an inch may be possible on elevated or grassy surfaces. Near critical fire weather conditions will remain possible over the San Luis Valley on Wednesday. .SPOTTER INFORMATION STATEMENT...
