...CRITICAL FIRE WEATHER AREA FOR PARTS OF THE CENTRAL HIGH PLAINS
AND SOUTHWARD ALONG THE LEE OF THE ROCKIES IN CO AND NM...

...Synopsis...
A low-amplitude midlevel trough and acco*panying strong
west-northwesterly flow will overspread the northern and central
Rockies, resulting in a deepening lee trough over the High Plains.
At the surface, low pressure will lift northeastward from western SD
into the Upper MS Valley, while an attendant cold front sweeps
southward across the central and southern High Plains.

...Central High Plains and southward along the lee of the Rockies in
CO and NM...
As the core of the strong/deep west-northwesterly flow impinges on
the central Rockies and adjacent High Plains, diurnal heating will
allow for the strong flow aloft to mix down to the surface. 20-30
mph sustained west-northwesterly surface winds (with higher gusts)
are expected from eastern WY into western NE and northeastern CO
behind the southward-advancing cold front. Here, a relatively cool
airmass could limit RH reductions to an extent, however, the
strong/gusty surface winds and very dry fuels will still result in
critical fire-weather conditions. Along the lee of the Rockies from
central CO into NM, downslope flow amid a warmer/drier antecedent
airmass will favor 10-15 percent minimum RH with 20-25 mph sustained
west-northwesterly surface winds.

...Mid-Atlantic...
A dry post-frontal airmass will be in place across much of the
Mid-Atlantic (minimum RH of 20-30 percent), however, generally light
surface winds are expected where the lowest RH will develop.
