####018001208#### FNUS21 KWNS 130753 FWDDY1 Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0153 AM CST Fri Dec 13 2024 Valid 131200Z - 141200Z ...Synopsis... A progressive mid-level shortwave trough is forecast to traverse the southern Rockies today, reaching central NM by peak heating. In response to the arrival of the wave, a lee cyclone across east/southeast CO will deepen, intensifying westerly downslope surface winds over the southern High Plains and lee of the Rockies. Sustained winds of 20-25 mph (gusting to 35-40 mph) are possible, given deep mixing and the approach of a 45-55 knot mid-level jet. The downslope trajectories, deep mixing and mild temperatures will support afternoon RH values of 12-15%. Despite several hours of elevated to critical meteorological conditions, the main limiting factor appears to be the lack of critically dry fuels. With seasonal ERC values of 60-80%, area fuels should be capable of supporting some elevated fire-weather risk, though conditions do not appear favorable for more widespread critical concerns. ..Lyons.. 12/13/2024 ...Please see www.spc.noaa.gov/fire for graphic product... $$ ####018001104#### FNUS22 KWNS 130754 FWDDY2 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0154 AM CST Fri Dec 13 2024 Valid 141200Z - 151200Z ...NO CRITICAL AREAS... ...Synopsis... In the wake of the progressive mid-level trough moving over the South Plains D1/Fri, shortwave ridging will rapidly develop over the western High Plains ahead of a second deepening trough farther west. The ridging will favor weak winds and relatively mild temperatures through much of the day. The ridge will break down ahead of the strengthening mid-level trough late in the day into early D3/Sun. Strong westerly winds aloft may support downslope flow west of a surface lee trough over parts of the Rockies and High Plains. However, the trough aloft is expected to be poorly timed with the diurnal cycle, supporting only modest surface winds and relatively poor overlap with critically low RH values. This should largely negate fire-weather concerns across the CONUS. ..Lyons.. 12/13/2024 ...Please see www.spc.noaa.gov/fire for graphic product... $$
