   Valid 291200Z - 051200Z

   An upper trough/low should be centered over the Four Corners region
   Saturday morning, and is then forecast to move eastward across the
   Plains on Day 4/Sunday, eventually reaching the Upper Midwest by Day
   5/Monday. Enhanced mid-level winds associated with this upper
   trough/low will remain over parts of the Southwest and southern
   Plains through Day 4/Sunday, and will elevate fire weather concerns
   across these areas.

   Medium-range guidance remains in good agreement depicting
   amplification of an upper ridge over the western CONUS and eastern
   Pacific from Day 5/Monday through the end of the forecast period.
   Another upper trough should develop southeastward from the
   northern/central Rockies into the Plains and eventually the MS
   Valley in the same time frame.

   ...Day 3/Saturday - Day 4/Sunday: Portions of the Southwest and
   Southern Plains...
   Strong/gusty winds and lowered RH values should develop on Day
   3/Saturday across portions of the Southwest into the southern Plains
   as enhanced mid-level winds remain across these regions. A
   40%/marginal area has been maintained with no changes. Uncertainty
   remains regarding RH values falling below 15% on a widespread basis,
   which precludes higher probabilities at this time.

   By Day 4/Sunday, the enhanced mid-level winds associated with the
   previously mentioned northeastward-moving upper trough will
   overspread mainly west TX to deep south TX along the Rio Grande. A
   40%/marginal area has been continued with no changes across this
   region as gusty northwesterly winds should develop, with limited
   confidence in the occurrence of both sustained winds above 20 mph
   and critically lowered RH values precluding a 70%/critical area.

   For Day 5/Monday and beyond, weaker mid-level flow is forecast over
   the Southwest and southern Plains, which should tend to limit the
   prospect for widespread critical fire weather conditions. Therefore,
   no probabilities have been included in this time frame.

   ...Day 3/Saturday - Day 4/Sunday: Portions of the FL Peninsula...
   A relatively dry low-level airmass is forecast to remain across much
   of the FL peninsula through at least Day 4/Sunday in the wake of a
   prior frontal intrusion. RH values may fall near to/below critical
   thresholds each afternoon across interior portions of the FL
   peninsula. However, forecast wind speeds do not appear sufficiently
   strong to support widespread critical fire weather conditions any
   day, which continues to preclude the introduction of 40%/marginal
