SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0357 PM CDT Sat Jun 14 2025 Valid 161200Z - 221200Z ...Days 3-4/Monday-Tuesday... On Day 3/Monday, a midlevel shortwave trough and related strong midlevel westerly flow will track eastward across the Great Basin during peak heating. Deep boundary-layer mixing into the strong flow aloft and a tightening surface pressure gradient will lead to critical fire-weather conditions from southern NV into southern UT. Thereafter, the midlevel shortwave trough and strong flow aloft will continue eastward across the Southwest on Day 4/Tuesday. Given a warm/dry air mass and increasingly dry fuels, critical fire-weather conditions are expected across parts of eastern AZ and western/central NM. ...Days 6-8/Thursday-Saturday... Deep-layer southwesterly flow will gradually strengthen across the Great Basin ahead of an evolving large-scale trough. As these strong winds overspread a deeply mixed air mass each afternoon, an expansive area of elevated to critical fire-weather can be expected. As the midlevel trough advances eastward across the Intermountain West into the weekend, strong northerly winds will overspread CA, supporting increasing fire-weather concerns over areas of receptive fuels. Higher probabilities may eventually be needed during this time frame as the overall timing/evolution of the large-scale trough becomes more clear. ..Weinman.. 06/14/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

WW 414 SEVERE TSTM CO NE SD WY 142040Z - 150300Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 414 NWS Storm Prediction Center Norman OK 240 PM MDT Sat Jun 14 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northeast Colorado The Nebraska Panhandle Extreme southwest South Dakota Eastern Wyoming * Effective this Saturday afternoon and evening from 240 PM until 900 PM MDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2 inches in diameter possible Scattered damaging wind gusts to 70 mph possible SUMMARY...A few thunderstorm clusters, and potentially a couple of supercells, are expected to form and spread eastward from eastern Wyoming into the Nebraska Panhandle and adjacent parts of far southwest South Dakota and northeast Colorado through late evening. Large hail of 1-2 inches in diameter and severe outflow gusts of 60-70 mph will be the main threats. The severe thunderstorm watch area is approximately along and 60 statute miles east and west of a line from 25 miles north northeast of Gillette WY to 60 miles southwest of Sidney NE. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 27020. ...Thompson Read more
