MD 0127 CONCERNING HEAVY SNOW FOR WEST TO NORTHWEST TEXAS
Mesoscale Discussion 0127
NWS Storm Prediction Center Norman OK
1056 AM CST Sun Feb 11 2024
Areas affected…West to northwest Texas
Concerning…Heavy snow
Valid 111656Z – 112100Z
SUMMARY…Periods of heavy snow with snowfall rates approaching 1
in/hour should continue into the early afternoon hours across
portions of west to northwest Texas.
DISCUSSION…Surface observations over the past 1-2 hours across
western TX have reported periods of visibility reductions down to
1/2 to 1/4 mile, indicative of moderate to heavy snowfall rates.
This trend is expected to persist for the next few hours as lift
within the left-exit region of an upper jet continues to coincide
with a mid-level deformation zone at around 700 mb. While the
dendritic growth zone is expected to remain somewhat shallow (around
50-100 mb deep), ascent through the 700-500 mb layer with lapse
rates approaching 7-8 C/km should continue to promote moderate to
heavy snowfall rates up to 1 inch/hour. Weak frontogenesis should
limit the potential for long duration snow bands, but latest
forecast guidance suggests that favorable overlap of mid/upper-level
ascent will linger over west to northwest TX through early
afternoon.
