####018002979#### FNUS28 KWNS 072139 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0438 PM CDT Sun Apr 07 2024 Valid 091200Z - 151200Z A closed low will propagate eastward across southern Arizona/southern New Mexico and into the central and southern Plains on D3-Tuesday, bringing an increase in surface winds but also potential for widespread wetting rainfall and cooler temperatures. The expected precipitation will help to moisten fuels and reduce fire weather concerns across portions of the Central/Southern Plains. Little to no rainfall is expected across portions of far western Texas, where fuels in this region will likely remain critically dry with periods of dry and breezy conditions creating Elevated to Critical fire weather. ...(D3 - Tuesday) Western Texas... As the upper-level low moves across western Texas, strong westerly flow aloft will overspread the Sierra Madre bringing further downslope warming and drying to an already very dry air mass across far western Texas into the Big Bend region. Relative humidity will drop as low as the single digits, with sustained winds approaching 20-25 mph (gusting 40-50 mph). A cold front will slide southward through the day bringing in cooler northwesterly flow, which will lead to an increase in relative humidity spreading north to south. This brings uncertainty in the duration of any potential Critical fire weather conditions, particularly on the northern fringe of the 40 percent probabilities where fuels are less sparse. As such, a trend to shift the 40 percent further south continues with this outlook. Across far western Texas into the Big Bend region eastward to the Edwards Plateau, fuels are critically dry with potential for very strong surface winds and single digit humidity. As such, a 70 percent Critical region was added with this outlook where conditions should be met for several hours. Strong post frontal northwesterly flow will overlap dry conditions along the southern Texas/Mexico border on D4 - Wednesday but coverage should remain too limited to warrant probabilities. Dry and breezy conditions will be possible across portions of eastern Colorado into western Kansas, where less rainfall is expected. However, a relatively cool continental air mass should keep relative humidity above critical thresholds. For D5 - D6 Thursday to Friday, high pressure will build across the Great Plains, keeping winds low where fuels remain dry. Late in the period D7 - D8 Saturday to Sunday, another western trough is projected to begin spreading enhanced westerly flow across the southwest into the Rockies, which may bring additional periods of fire weather concerns to the central/southern Plains as well as some drying of fuels across portions of the Desert Southwest. ..Thornton.. 04/07/2024 ...Please see www.spc.noaa.gov/fire for graphic product... $$ ####018000451#### FNUS38 KWNS 072139 PFWF38 DAY 3-8 FIRE WEATHER OUTLOOK AREAL OUTLINE NWS STORM PREDICTION CENTER NORMAN OK 0438 PM CDT SUN APR 07 2024 VALID TIME 091200Z - 151200Z FIRE WEATHER OUTLOOK POINTS DAY 3-8 ...
