####018001216#### FNUS21 KWNS 140801 FWDDY1 Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0200 AM CST Sat Dec 14 2024 Valid 141200Z - 151200Z ...NO CRITICAL AREAS... ...Synopsis... A progressive mid-level trough moving over the Southern Plains will rapidly move eastward as shortwave ridging develops over the Rockies and High Plains in its wake. A second mid-level trough farther west will begin to approach later this evening and overnight as increasingly strong westerly flow overspreads the Plains again. The ridging will initially favor weak surface winds and relatively mild temperatures through much of the day before the approaching trough aids in developing a lee cyclone over the central and northern High Plains. The deepening low and strong westerly winds aloft may support downslope flow over parts of the Rockies and High Plains with gusts of 20-30 mph. However, the late arrival of the trough, poorly timed with the diurnal cycle, will favor relatively poor overlap with low RH values. This should limit fire-weather concerns across the CONUS. ..Lyons.. 12/14/2024 ...Please see www.spc.noaa.gov/fire for graphic product... $$ ####018001501#### FNUS22 KWNS 140803 FWDDY2 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0202 AM CST Sat Dec 14 2024 Valid 151200Z - 161200Z ...NO CRITICAL AREAS... ...Synopsis... As the mid-level trough ejects over the central Rockies and into the Plains early D2/Sunday, a lee low and trailing surface trough will quickly deepen across parts of the High Plains. At the same time, a cold front will approach from the interior West. Aided by strong mid-level westerlies at the base of the trough and downslope pressure gradients, several hours of strong surface winds (20-30 mph) are likely across parts of the central High Plains. These strong winds may briefly overlap with areas of moderately low RH (~30%) across western NE and eastern WY. Farther south into eastern NM and far West TX, lower RH will remain possible with more mild temperatures and diurnal minimums of 20-25%. However, winds here are expected to be slower and more transient, owing to the weaker surface pressure falls and flow aloft. The net result will be a few hours of locally dry and breezy conditions in the lee of the Rockies where fuels are somewhat dry. While there is some risk, fire-weather concerns are not expected to be widespread, given the brief nature of the strong winds and lower RH, as well as the passage of the cold front Sunday evening. ..Lyons.. 12/14/2024 ...Please see www.spc.noaa.gov/fire for graphic product... $$
