  6. SPC 1300Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0740 AM CDT Mon Mar 18 2024 Valid 181300Z - 191200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON ACROSS CENTRAL FL AND MUCH OF THE FL ATLANTIC COAST... ...SUMMARY... Isolated large hail and wind damage is possible this afternoon across central Florida and along much of the Florida Atlantic coast. ...FL this afternoon... A northern stream shortwave trough will dig from the mid MS Valley this morning to the southern Appalachians this evening and off the Atlantic coast by early Tuesday. An associated stalled surface front across north FL this morning will begin to accelerate southeastward across the peninsula this evening through early Tuesday. The more pronounced midlevel height falls and forcing for ascent will pass north of FL, leaving shallow ascent along the front and/or differential heating boundaries (from convection moving inland from the northeast Gulf of Mexico this morning) to focus thunderstorm development. Forecast soundings suggest that moderate buoyancy (MLCAPE near 1500 J/kg), steep low-level lapse rates and 50 kt midlevel flow with relatively straight hodographs could support a supercell capable of producing isolated large hail (1-1.75 inches in diameter) and damaging gusts near 60 mph. The severe threat will peak by early-mid afternoon and then diminish into this evening. ...AZ/southern CA through this evening... As part of a Rex block, a closed low over AZ will drift westward today as an embedded speed max pivots from northern AZ toward southern CA. Low-level moisture will remain modest, but cool midlevel temperatures and daytime heating will contribute to at least weak buoyancy (SBCAPE of 250-750 J/kg). A few clusters of storms will form in the main band of ascent over the rim this afternoon, while other storms are expected to spread southwestward off the higher terrain toward the southern CA coast. The threat for severe storms will remain quite low, but the strongest storms could produce gusty outflow winds and small hail. ..Thompson/Dean.. 03/18/2024 Read more View the full article

  9. Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0359 AM CDT Mon Mar 18 2024 Valid 211200Z - 261200Z ...DISCUSSION... Medium-range models suggest that a blocking pattern evolving across the northeastern Pacific may be relatively short-lived, with flow across the central into eastern mid-latitude Pacific becoming more progressive. As a high initially centered near or southwest of the Gulf of Alaska breaks down, it appears that troughing within a couple of initial streams to its east will come in phase and contribute to amplifying larger-scale troughing developing inland of the Pacific coast early next weekend, then into the Great Plains by early next week. Embedded short waves progressing through this regime could provide support for significant surface cyclogenesis to the lee of the Rockies, particularly by next Sunday into Monday. There appears a general consensus among latest guidance that a developing cyclone across the Texas/Oklahoma Panhandle vicinity, trailing dryline southward into northwest Texas, and surface front extending east-northeastward across Kansas into the lower Missouri Valley could provide focus for organized severe thunderstorm development Sunday afternoon into Sunday night. The cyclone may then migrate northeastward along the front across the lower Missouri Valley into the Upper Midwest Monday through Monday night, accompanied by a potentially more widespread severe weather threat across the southeastern Great Plains and lower/middle Mississippi Valleys. However, potential also exists for this to be considerably modulated by cold air, initially banked up against the northern U.S. and Canadian Rockies into much of the upper Mississippi Valley, which may tend to nose further southward through the high plains prior to the emergence of the primary short wave trough. Furthermore, in the wake of an amplifying mid-level trough and associated cyclogenesis still forecast offshore of the southern Atlantic Seaboard, low-level moistening on southerly return flow off the Gulf of Mexico may not be optimal.
