.PREV DISCUSSION... /ISSUED 1225 AM CST Thu Jan 21 2021/
A departing surface low and building surface high across the
northern CONUS will help cooler air filter into the central U.S.
today and into tomorrow. Weakening pressure-gradient winds will also
help to minimize the fire weather potential for the Plains. To the
south, a plume of mid-level moisture will continue to advect into
the western Gulf states, and given weak ascent ahead of the Baja
California shortwave trough, will bring light precipitation chances
and low fire weather concerns. Low relative humidity values in the
30-40% range are possible for the southern half of the FL peninsula
(where fuels have been gradually drying), but weak winds under a
surface high will negate any serious concerns.
