Day 1 Fire Weather Outlook

0933 AM CST Tue Feb 16 2021



Valid 161700Z - 171200Z



...NO CRITICAL AREAS...



No forecast changes are needed. Morning surface observations through

the lower CO river valley show winds increasing amid surface

pressure falls over the Four Corners. Cold air advection just above

the surface along with diurnal heating will allow for steep

low-level lapse rates favorable for supporting wind gusts up to

30-40 mph this afternoon. Relative humidity values near 15-20%

remain likely, but recent fuel analyses continue to show unready

fuels over the region.

...Synopsis...

With continued, but weakening, high pressure across areas east of

the Divide, cold temperatures and precipitation are expected to keep

fire weather concerns very low today. Broad upper-level troughing

will continue over most of the U.S. with shortwave trough moving

through this parent trough and into the southern Plains. This

shortwave will keep strong mid-level flow across the Colorado River

Valley. RH in southern Nevada into southwestern Arizona could fall

as low as 15-20%. Localized elevated conditions are possible as

surface winds increase to 15-25 mph in conjunction with a deepening

surface trough in the High Plains to the east. However, sparse,

marginal fuels preclude highlights.
