   Medium range guidance is in fairly good agreement during the day 3-8
   period. Fire weather concerns will generally remain confined to the
   southern Plains during this time, mainly in the day 4/Sun-day 6/Tue
   time frame. 

   One difference noted is a shortwave trough ejecting across the
   southern Rockies on day 4/Sun depicted by the GFS. The ECMWF
   maintains more zonal westerly flow across the southern Rockies
   during this time. However, both have strong deep layer westerlies
   with a well-defined lee trough developing. This should lead to at
   least elevated fire potential across the southern High Plains on day
   4/Sun with gusty surface southwesterly winds and low RH continuing
   in conjunction with dry fuels. On day 5/Mon, a larger-scale upper
   trough will deepen over the western U.S. and strong southwesterly
   deep layer flow will continue across the southern Rockies. Another
   lee low/surface trough will develop along the central and southern
   high Plains with gusty downslope winds contributing to another day
   of elevated fire weather potential. 

   By day 6/Tue, the western trough will eject eastward into the Plains
   during the nighttime hours. Ahead of the trough, deep layer
   southwesterly flow will increase and another, stronger lee cyclone
   is expected to develop and shift east across parts of the
   central/southern Plains and eventually toward the MS River. There is
   some discrepancy between medium range guidance in the exact strength
   and track of the surface low and this could impact how widespread
   the development of critical fire weather conditions becomes.
   Regardless, this is a favorable pattern for strong southwest surface
   winds and very low RH conditions across the southern high Plains and
   elevated to critical fire weather conditions are expected. 

   By days 7-8/Wed-Thu, fire weather concerns will diminish as a highly
   amplified ridge builds over the eastern Pacific and the upper trough
   shifts eastward over the eastern U.S.
