U.S. Day 2 Fire Weather Outlook
ZCZC SPCFWDDY2 ALL FNUS22 KWNS 260652 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0152 AM CDT Fri Apr 26 2024 Valid 271200Z - 281200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHERN AND CENTRAL HIGH PLAINS... ...Synopsis... A strong mid-level jet streak will round the western trough on Saturday, with strong lee cyclogenesis resulting across the High Plains. Strengthening flow amid very dry conditions will lead to Critical fire weather concerns across portions of the southern High Plains into the central High Plains. ...Southern and Central High Plains... A deeply mixed airmass is expected to be in place by Saturday afternoon across portions of eastern New Mexico into far southeastern Colorado and eastward into the Oklahoma/Texas Panhandles. In these regions, sustained surface winds 20-30 mph will overlap afternoon relative humidity reductions to around 5-10 percent. While some spotty Extremely Critical conditions are possible, fuels do not yet support inclusion of an Extremely Critical area at this time. Conditions will be monitored for higher end potential. ..Thornton.. 04/26/2024
U.S. Day 3-8 Fire Weather Outlook
ZCZC SPCFWDD38 ALL FNUS28 KWNS 252121 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0421 PM CDT Thu Apr 25 2024 Valid 271200Z - 031200Z A strong mid-level trough will be present across the Southwest CONUS at the beginning of the period. This trough will shift into the Upper Midwest on Sunday/Monday. Beyond Monday a more zonal pattern should lead to relatively benign fire weather conditions for the day 4-8 period. ...Day 3/Sat - Southern High Plains... A very strong mid-level jet streak will round the base of the mid-upper level trough and eject across the southern High Plains Saturday afternoon. A deeply mixed airmass is present across this region which will allow for some of this stronger flow to mix to the surface. In addition, a developing lee cyclone and the associated tightening of the surface pressure gradient will also aid in stronger winds at the surface. Relative humidity is expected to be around 8 to 12 percent with surface sustained winds around 25 to 35 mph. While this technically meets the criteria for extremely critical fire weather conditions, it does not appear fuels are quite to the extremely critical fuel dryness needed to support true extremely critical fire weather. However, conditions will be monitored for this higher end potential. ...Day 4/Sunday - Southern High Plains... Some dry and breezy conditions are possible in the southern High Plains again on Sunday. These conditions should be mostly confined to southeast New Mexico and vicinity where stronger mid-level flow should be present and at least some weak lee cyclogenesis is possible with a passing weak mid-level shortwave trough. ..Bentley.. 04/25/2024
