Areas affected...eastern WY...far north-central CO
Concerning...Severe potential...Watch unlikely=20
Valid 051851Z - 052045Z
Probability of Watch Issuance...20 percent
SUMMARY...Isolated to widely scattered thunderstorms are likely to
develop and intensify through the mid-late afternoon. Isolated
large hail and severe gusts are the primary threats.
DISCUSSION...Visible satellite imagery shows developing
thunderstorms near the I-25 corridor in southeast WY and other
deepening convection over the CO Front Range. Relatively moist
upslope flow into the Cheyenne Ridge is maintaining 40s dewpoints
into Weld Co., CO and from the NE Panhandle into far eastern WY.=20
Strong surface heating will contribute to weak buoyancy with upwards
of 500-1000 J/kg MLCAPE over eastern WY. Although the mid to
upper-level ridge extends from KS northwestward into eastern WY, the
magnitude of moisture coupled with upslope flow will lead to at
least isolated to widely scattered thunderstorms developing by
mid-late afternoon. Deep-layer shear will remain limited and only
favor multicellular storm modes, but the very steep low to mid-level
lapse rates will promote both hail growth and potential severe gusts
with the stronger cores.
