   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF THE CENTRAL AND NORTHERN
   HIGH PLAINS...

   No changes to the ongoing forecast. Locally elevated conditions are
   possible as northerly/northeasterly winds continue in the Sacramento
   Valley into the afternoon. Additionally, locally elevated conditions
   are also possible in parts of the Upper Midwest. These conditions
   will be both marginal and brief and no highlights will be added.

   ...Synopsis...
   A deep mid-level trough over the northern Rockies is forecast to
   intensify as it moves eastward and ejects over the northern/central
   Plains today and tonight. As the trough moves east, a lee low/trough
   will quickly deepen, supporting strong surface winds over the
   Plains. A cold front approaching from the west will move through the
   Great Basin also supporting strong surface winds over the Rockies.
   Dry and windy conditions will favor critical fire-weather concerns
   across the Intermountain West and western Plains through this
   evening.

    ...Central and northern Plains...
   As the upper-level trough approaches from the west this morning,
   southerly surface winds are expected to rapidly increase over much
   of the High Plains. Winds should continue to intensify through the
   day as low pressure and the trailing lee trough deepen.
   South/southwesterly gusts of 20-30 mph are possible along with RH
   values below 25%. RH will be considerably higher farther east, as
   low-level moisture advects northward. Still, strong gusts of 25-30
   mph are likely with pockets of afternoon RH as low as 25-30%. Strong
   winds will accelerate drying of fine fuels after recent scattered
   precipitation, with critically dry fuels expected over much of the
   central and northern Plains by this afternoon. With the potent
   combination of strong winds and low RH likely over several hours,
   widespread elevated to critical fire-weather conditions are
   expected.
     
   ...Intermountain West...
   Across parts of western CO/WY, strong southwesterly winds are
   expected ahead of the cold front moving out of the eastern Great
   Basin. Aided by the strong flow aloft, wind gusts of 25-30 mph are
   likely. Dry southwesterly flow and warm temperatures will support
   afternoon RH values below 20%. Meteorological conditions are quite
   conducive to fire spread. Despite some recent drying, area fuels are
   not particularly dry after rainfall in the last 48 hours. However,
   given the magnitude of the wind and relatively dry conditions,
   several hours of elevated to near-critical fire-weather conditions
   still appear likely, especially over parts of western CO and eastern
   UT.
