   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHERN AND
   CENTRAL HIGH PLAINS...

   ...Synopsis...
   A midlevel trough will cross the Southwest during the day, while a
   related 60-70 kt southwesterly midlevel jet overspreads the southern
   into central High Plains. In response, a lee cyclone will rapidly
   deepen over eastern CO/western KS, while a southward-extending
   dryline sharpens over parts of west TX. This large-scale pattern
   evolution will favor an expansive area of high-end critical
   fire-weather conditions across the southern into central High Plains
   during the afternoon. 

   ...Southern into Central High Plains...
   Behind the dryline, strong downslope warming/drying and diurnal
   heating will result in a deep/dry boundary layer, characterized by
   surface temperatures in the 80s and single-digit to lower-teens RH.
   Here, a tightening surface pressure gradient peripheral to the
   deepening lee cyclone, coupled with mixing into the strong
   deep-layer southwesterly flow, will yield 30 mph sustained
   southwesterly surface winds (with gusts upwards of 45 mph) across
   eastern NM into southeastern CO. While confidence is high in the
   development of these extremely critical meteorological conditions, a
   potential lack of abundant and very dry fuels precludes Extremely
   Critical highlights at this time.

   Valid 251200Z - 011200Z

   An active fire weather pattern will become situated over the
   southern High Plains late this week through the weekend. The passage
   of multiple mid-level troughs will encourage surface cyclone
   development and the eastward surge of a dryline each day
   Thursday-Sunday along the southern High Plains. Critically dry and
   windy conditions will become situated behind the dryline each day,
   with 70% Critical probabilities maintained where very windy and dry
   surface conditions will coincide for several hours during the
   afternoon. Furthermore, locally Extremely Critical surface winds/RH
   cannot be ruled out over portions of eastern New Mexico into far
   western Texas for Day 3/Thursday or Day 5/Saturday, when the core
   mid-level jet stream from both upper-level troughs overspread the
   region. By early next week, the ejection of these mid-level troughs,
   in favor of upper ridging, will encourage a more quiescent fire
   weather pattern over the southern High Plains, though dry surface
   conditions should persist.
