0623 AM CST Fri Nov 08 2024
Areas affected...southeast Colorado...far northeast New Mexico...and
the western OK Panhandle.
Concerning...Heavy snow
Valid 081223Z - 081630Z
SUMMARY...Heavy snow will develop across southeast Colorado and
vicinity this morning.
DISCUSSION...An upper-level low across New Mexico has started to
become negatively tilted this morning. As this has occurred, a broad
region of ascent has overspread the southern Plains, evidenced by
widespread lightning activity. In addition, strong frontogenesis
across the Texas Panhandle has resulted in a more focused region of
ascent. The heavier precipitation associated with this enhanced area
of UVV will migrate northwestward into the cold airmass across
southeast Colorado over the next few hours. In addition, a easterly
low-level jet, currently around 35 knots (per DDC VWP) and expected
to strengthen to around 45 knots, will result in strengthening
isentropic ascent. The combination of these factors will result in a
favorable region across southeast Colorado and vicinity with
snowfall rates of 1 to 2 inches per hour, likely starting between
13Z and 14Z.
