Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
1144 PM CST Sat Mar 10 2018
Valid 131200Z - 141200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
Isolated thunderstorms are expected across portions of the Great
Basin and Sierra Nevada Tuesday.
...Great Basin/Sierra Nevada...
Strong Pacific cold front will cross the Sierra Nevada around 18z
then into the Great Basin by 14/00z. Strong height falls and cooling
mid-level temperatures will steepen lapse rates as profiles moisten
within exit region of jet. As a result, buoyancy should increase
such that convection is expected to deepen along a corridor from the
higher terrain of eastern CA into NV. Strongest updrafts are
expected to attain heights necessary for lightning discharge and low
thunder probabilities have been added to this region.
