..Wendt.. 04/19/2021

.PREV DISCUSSION… /ISSUED 0153 AM CDT Mon Apr 19 2021/

…Synopsis…
A positively tilted mid-level shortwave trough will dig from the
Northwest into the Great Basin today. As it moves southeastward,
cyclogenesis is expected in portions of the Southwest. A
strengthening pressure gradient as a result of this cyclogenesis and
deep mixing bringing stronger mid-level flow to the surface will
combine for gusty winds from the northern Great Basin into the
Southwest. Dry conditions will be present across this region and
therefore, some fire weather concerns are expected. The primary
concern will be across portions of eastern Nevada, Utah, northern
Arizona, and western Colorado where some dry fuels are present and
the strongest winds are expected.

Additionally, some dry and breezy conditions are expected in the
Texas Panhandle as cyclogenesis strengthens across New Mexico.
However, the longevity and strength of the winds preclude the need
for an elevated delineation at this time.
