320 FNUS21 KWNS 011610 FWDDY1 Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1109 AM CDT Mon Jun 01 2020 Valid 011700Z - 021200Z ...CRITICAL FIRE WEATHER AREA FOR PARTS OF EASTERN NEVADA INTO WESTERN UTAH... The previous forecast remains largely on track. Current visible satellite depicts partly cloudy conditions across the Northeast, with RH dropping below 40% amidst surface northwesterly winds increasing above 10 mph in several locales along the New England coastline. Continued boundary layer heating suggests that elevated conditions will occur through the afternoon hours across parts of New England. A very slight westward expansion of the critical area was also made based on the latest model guidance. Please see the previous forecast below for more details. ..Squitieri.. 06/01/2020 .PREV DISCUSSION... /ISSUED 0109 AM CDT Mon Jun 01 2020/ ...Synopsis... Upper-level troughing will continue over the West Coast with an upper low beginning to become cutoff off Baja/southern California. An upper ridge over the central CONUS will flatten as multiple mid-level shortwave troughs traverse along its northern periphery. A surface pressure trough will extend out of the Lower Colorado River Valley and into the eastern Great Basin. ...Great Basin and Four Corners... Critical conditions are expected across eastern Nevada and western Utah today as south-southwest sustained surface winds of 15-25 mph develop amid minimum RH of 8-15%. Elevated conditions are expected across central Nevada into northern Arizona and northward through eastern Utah and northwest Colorado. Of particular concern are these elevated/critical conditions developing after recent lightning across much of the delineated area. Locally critical winds/RH are likely across portions of southern Wyoming today, however, fuel conditions will mitigate the threat. Thunderstorms are expected to develop across portions of the Four Corners and Colorado Rockies today. However, storm motions will be slower than in days past and this will be multiple consecutive days of thunderstorms, likely leading to increased values of fuel moisture. ...Northeast and New England... Elevated conditions are likely to develop across portions of New Jersey, southern New York and into southern/eastern New England. Northwesterly winds of 10-20 mph and minimum RH of 25-35% are likely to develop by mid-day and continue through the afternoon. The elevated area was confined by recent rainfall and where winds will be strong enough to meet elevated criteria. ...Please see www.spc.noaa.gov/fire for graphic product... $$
