Day 1 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

1049 AM CDT Sat Apr 13 2024



Valid 131700Z - 141200Z



...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF CENTRAL KANSAS...



Critical fire weather appears probable along the western fringe of

greater surface moisture across eastern Kansas. Here, RH of near to

just below 20% is likely along with low-level pressure gradients

remaining strong enough into the afternoon to support around 20 mph

winds with higher gusts.

.PREV DISCUSSION... /ISSUED 0111 AM CDT Sat Apr 13 2024/



...Synopsis...

Elevated fire weather conditions are anticipated across a broad

swath of the southern Great Basin to the southern/central Plains

this afternoon. However, the fire weather threat will likely be

focused primarily across portions of the southern High Plains where

the overlap of receptive fuels and dry/windy conditions will be

greatest.



...Southern High Plains to northern KS...

05 UTC surface observations show somewhat poor overnight RH recover

with RH values remaining in the 15-30% range across eastern NM into

far western TX. Additionally, regional 00 UTC soundings sampled very

dry boundary-layer conditions across NM and western TX. This dry air

mass will spread to the east/northeast through the afternoon as

southwesterly winds increase in tandem with a deepening lee trough.

Widespread RH values in the low teens to low 20s will likely

coincide with 15-20 mph winds (gusting to 25-30 mph). Elevated fire

weather conditions will likely be widespread across the southern

High Plains into western TX, OK, and KS. However, rainfall over the

past 72 hours across parts of TX and OK has limited fuel

receptiveness based on recent rainfall analyses and fuel reports.

Early spring green up is also more prevalent with eastern extent,

which will further limit fire potential. Therefore, the Elevated

risk area delineates where the best overlap of dry fine fuels and

dry/windy conditions should occur.



...Upper Mississippi Valley...

Southerly winds are expected to strengthen through the day in

response to the deepening lee trough. Very limited moisture return

until late in the day, coupled with strong diurnal warming, should

result in areas of 25-35% RH with 15-20 mph winds. Localized

elevated fire weather conditions will be possible across parts of

IA, MN, and southwestern WI, but are expected to remain sufficiently

limited spatially and temporally to negate the need for additional

highlights.
