...Synopsis...

A mid-level trough will traverse the central Rockies while surface

high pressure overspreads much of the western and central CONUS

tomorrow, Wednesday February 24th. While cool and/or moist

conditions are expected to limit wildfire potential across much of

the CONUS, a localized threat for wildfire spread may develop across

portions of the southwest U.S (mainly southern Arizona and New

Mexico), ahead of a southward approaching cold front. Before

temperatures cool, diurnal mixing may promote 15-20% RH and 15-20

mph sustained westerly winds around afternoon peak heating. However,

fuels remain poorly receptive to fire spread, precluding any fire

weather highlights. 



In addition, southward surging high pressure will also support the

development of a strong pressure gradient across southern

California, with dry and breezy offshore conditions likely beginning

on Wednesday evening. Similar to areas farther east, fuel

receptiveness to fire spread remains meager, with no fire weather

delineations made at this time. However, several areas across the

southern Transverse/Peninsular Ranges have been relatively devoid of

meaningful precipitation accumulations for the past two weeks. As

such, an Elevated highlight may be introduced if the driest/windiest

conditions may overlap with diurnal heating, potentially prompting

the finest fuels to become more receptive to fire spread.
