Valid 131200Z - 141200Z



...CRITICAL FIRE WEATHER AREA FOR PARTS OF THE DESERT SOUTHWEST....



...Synopsis...

An upper-level trough across the western U.S. will translate

eastward across the Rockies with strong mid-level flow overspreading

much of the Southwest. Lee troughing will encourage strong westerly

winds and dry downslope conditions across the Southwest and High

Plains. With little recent rainfall and above normal temperatures

overlapping the increased surface winds, elevated fire-weather

conditions are likely.



...Southwest...

The upper trough and attendant mid-level jet are forecast to

intensify and aid in the development of  stronger winds within a

well-mixed boundary layer across much of the Southwest. Westerly

downslope flow of 20-30 mph amid RH values below 15% will support

widespread dry and windy conditions across southeastern AZ into

southern NM Tuesday. Several days of above-normal temperatures and

poor humidity recoveries suggest additional drying of already

receptive fuels is likely. Widespread elevated to critical fire

weather conditions are likely across parts of the Southwest Tuesday

afternoon and evening.



...Red River of the North...

As the upper trough intensifies to the west, an elongated area of

low pressure will deepen near the international border. Strong

southerly winds are likely for another day east of the surface

trough/low. Persistent above-normal temperatures should maintain low

RH below 30% and dry fuels. With southerly gusts to 20 mph, several

hours of elevated fire-weather conditions appear likely across the

eastern Dakotas and western MN.
