URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 674 NWS Storm Prediction Center Norman OK 1245 PM MDT Tue Sep 17 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of South-Central and Southeast Colorado Eastern New Mexico * Effective this Tuesday afternoon and evening from 1245 PM until 700 PM MDT. * Primary threats include... Scattered damaging winds likely with isolated significant gusts to 75 mph possible Isolated large hail events to 1.5 inches in diameter possible SUMMARY...Thunderstorms that have developed over the higher terrain of the southern/central Rockies will continue to move quickly east-northeastward this afternoon and early evening. They should also intensify over the next several hours while posing a threat for mainly severe damaging winds up to 65-75 mph. Isolated large hail around 1-1.5 inches in diameter may also occur. The severe thunderstorm watch area is approximately along and 60 statute miles east and west of a line from 35 miles east northeast of Pueblo CO to 5 miles southwest of Roswell NM. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). PRECAUTIONARY/PREPAREDNESS ACTIONS...

MD 2079 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR EASTERN WYOMING...NORTHEASTERN/EAST CENTRAL COLORADO...ADJACENT SOUTHWESTERN SOUTH DAKOTA AND WESTERN NEBRASKA
Mesoscale Discussion 2079 NWS Storm Prediction Center Norman OK 0208 PM CDT Tue Sep 17 2024 Areas affected...eastern Wyoming...northeastern/east central Colorado...adjacent southwestern South Dakota and western Nebraska Concerning...Severe potential...Watch possible Valid 171908Z - 172145Z Probability of Watch Issuance...60 percent SUMMARY...High-based thunderstorm development appears increasingly probable across and east of the Front Range by 3-5 PM MDT, accompanied by increasing potential for strong to severe wind gusts while spreading through the adjacent high plains through early evening. One or two severe weather watches are possible, though timing remains somewhat uncertain. DISCUSSION...Downstream of a vigorous short wave trough pivoting northeastward toward the Wyoming/Colorado Rockies, southwesterly mid/upper flow is in the process of strengthening. This is forecast to include speeds of 40-70+ kt in the 500-300 mb layer across and northeast of the Front Range, above a boundary layer across the high plains which is becoming strongly heated and deeply mixed. Surface temperature/dew points already have commonly reached 40-45 degrees across much of eastern Colorado and Wyoming. While boundary-layer moisture content is generally low, various model output indicates that steepening lower/mid-tropospheric lapse rates, along the leading edge of mid-level cooling now approaching the Front Range, will support increasing high-based convective development along and east of the higher terrain by 20-22Z. Updrafts might not be particularly intense, at least initially as activity begins to spread toward the high plains, but sub-cloud evaporative cooling and downward mixing of cloud-bearing mean flow on the order of 50 kt are likely to contribute to the risk for strong to severe downbursts. Thereafter, the potential for strong to severe wind gusts may gradually become more widespread as convective outflow becomes more widespread and strengthens while surging northeastward and eastward. ..Kerr/Gleason.. 09/17/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0411 PM CDT Tue Sep 17 2024 Valid 191200Z - 251200Z An active mid-level flow regime is expected across the CONUS over the next seven days. A mid-level trough and speed max will pass through the southern Rockies and Plains late this week and into the weekend. A strong lee cyclone will support gusty winds and low humidity. However, widespread rainfall is also expected. Behind the trough, high pressure and higher-latitude zonal flow will develop over the Northwest early next week. Some potential for easterly offshore could develop, but significant forecast uncertainty is present in the medium range. This suggests the threat for fire-weather conditions is relatively low. ...Southern Plains... As the aforementioned trough ejects eastward, strong southwesterly flow aloft will overspread much of the southern Rockies and High Plains. Currently, area fuels are not receptive to fire spread. Additional precipitation also appears likely over the next few days. However, strong lee cyclogenesis is also expected to bolster surface winds (20-25 mph) over much of the Plains through the end of the week and into the early weekend. Some potential for drying mid week could support at least some low-end fire-weather concerns if fuels are able to dry. While this is uncertain, some risk for fire-weather concerns is possible. ...West Coast... Late in the weekend and into early next week, some model guidance shows the development of high pressure across the Great Basin, while broad weak troughing could intensify off the West Coast. Should this occur, offshore pressure gradients may develop, and could support some dry and breezy conditions across parts of CA and the coastal ranges of WA and OR. However, forecast and fuels uncertainty is significant, and no probabilities will be introduced until a clearer solution develops. ..Lyons.. 09/17/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

Some potential for easterly offshore could develop, but significant forecast uncertainty is present in the medium range. This suggests the threat for fire-weather conditions is relatively low. ...Southern Plains... As the aforementioned trough ejects eastward, strong southwesterly flow aloft will overspread much of the southern Rockies and High Plains. Currently, area fuels are not receptive to fire spread. Additional precipitation also appears likely over the next few days. However, strong lee cyclogenesis is also expected to bolster surface winds (20-25 mph) over much of the Plains through the end of the week and into the early weekend. Some potential for drying mid week could support at least some low-end fire-weather concerns if fuels are able to dry. While this is uncertain, some risk for fire-weather concerns is possible. ...West Coast... Late in the weekend and into early next week, some model guidance shows the development of high pressure across the Great Basin, while broad weak troughing could intensify off the West Coast. Should this occur, offshore pressure gradients may develop, and could support some dry and breezy conditions across parts of CA and the coastal ranges of WA and OR. However, forecast and fuels uncertainty is significant, and no probabilities will be introduced until a clearer solution develops. ..Lyons.. 09/17/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
