Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1017 AM CST Tue Jan 21 2020 Valid 211700Z - 221200Z ...NO CRITICAL AREAS... No changes and please see the discussion below for more details. ..Nauslar.. 01/21/2020 .PREV DISCUSSION... /ISSUED 1256 AM CST Tue Jan 21 2020/ ...Synopsis... An upper-level trough will continue to push southeastward into the Florida Peninsula today. At the surface, a stalled southwest-northeast boundary will sit across the Bahamas. A surface cyclone will develop along the boundary in response to the approaching trough. This will strengthen north-northwesterly flow down the Florida Peninsula during the afternoon. Surface winds are likely to reach 10-15 mph in parts of central and southern Florida. While the airmass will be rather dry, cold air advection during the day will tend to keep temperatures cooler and RH falling much below 40% on a broad basis. Locally elevated conditions are possible, however, where this marginally lowered RH can overlap with the stronger surface winds. This is most likely to occur within west-central Florida and adjacent areas of southern Florida. Farther north, temperatures are more likely to be cooler as well as winds likely weaker. Without more favorable fuel dryness, no elevated highlights will be introduced. ...Please see www.spc.noaa.gov/fire for graphic product... Day 2 Fire Weather Outlook Storm Prediction Center Norman OK 0134 PM CST Tue Jan 21 2020 Valid 221200Z - 231200Z ...NO CRITICAL AREAS... No changes and please see the discussion below. ..Nauslar.. 01/21/2020 .PREV DISCUSSION... /ISSUED 0123 AM CST Tue Jan 21 2020/ ...Synopsis... Surface high pressure is expected to remain in place across areas east of the Mississippi River on D2/Wednesday. The surface low east of the Florida coast will begin to progress east-northeastward during the day, reducing the pressure gradient across the Southeast. Across the Plains, an upper-level trough will bring precipitation from the southern/central Plains into the upper-Midwest. Cool/cold temperatures and precipitation will limit the fire weather threat across much of the country. There are some indications that locally elevated conditions could develop within southern Georgia into portions of the Florida Peninsula before the surface winds relax during the afternoon/evening. However, there is a great deal of variance within guidance as to where low RH will overlap with surface winds of 10-15 mph. With this uncertainty in mind, no elevated areas are warranted at this time. ...Please see www.spc.noaa.gov/fire for graphic product...
