Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
1234 AM CDT Mon Mar 19 2018

Valid 211200Z - 221200Z


Little if any thunderstorm activity is forecast on Wednesday.

A large, cyclonically curved jet streak will depart the southeastern
states with upper low moving from the Mid Atlantic to just offshore
coastal New England. An associated surface low will remain over the
western Atlantic as well, with high pressure centered over the
length of the MS Valley. To the west, an upper low will exist just
off the coast of British Columbia with a surface trough developing
southward across the Pacific Northwest and into northern CA by
Thursday morning. Widespread precipitation will occur over much of
the West, but little if any instability will be present to support
thunderstorms. While an isolated lightning strike is possible across
the Sierra and/or Great Basin, the probability appears too low to
denote a general thunderstorm outlook.
