SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0128 AM CDT Fri May 19 2017 Valid 191200Z - 201200Z ...Synopsis... A shortwave trough is expected to move through the base of its parent upper low (centered over the central Rockies) into the central Plains this evening. The progression of this shortwave trough will induce some modest easterly motion of the parent upper low into the Plains with this eastward transition helping to push a cold front southward through the central and southern Plains. Recent surface analysis places this cold front from a low in northeast KS southwestward to another low in the northern TX Panhandle. A dryline extends southward from the northern TX Panhandle low south-southwestward through the Permian Basin to far southwest TX. Expectation is for the TX Panhandle low to track northeastward ahead of the previously mentioned shortwave trough while the cold front surges southward. By 00Z Saturday, this low will likely be near northeast OK/southeast KS with the cold front extending southwestward to another low near the Permian Basin. ...Southern NM into West TX... Dry conditions are anticipated this afternoon behind the aforementioned dryline from southern NM eastward into west TX. Temperatures are not expected to be particularly warm by dry antecedent conditions will still support afternoon RH values from 8 to 15 percent. Mid-level flow will be weakening throughout the day and the pressure gradient will not be particularly strong. These factors should mitigate wind speeds somewhat with most areas experiencing sustained winds below 20 mph. Isolated locations may see sustained winds over 20 mph for an hour or two. These meteorological conditions will support an elevated to locally critical fire weather threat in areas where fuels are dry. ..Mosier.. 05/19/2017 ...Please see www.spc.noaa.gov/fire for graphic product...
