Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0359 AM CDT Mon Jun 17 2024 Valid 201200Z - 251200Z ...DISCUSSION... Models are in good agreement showing minimal severe potential for much of the period, with generally weak winds aloft across the CONUS and an upper high over much of the East. There is some indication that the northern-stream may become more active along the US/CA border starting around Saturday/D6 or Sunday/D7, mainly from the upper MS Valley across the Great Lakes. Instability would appear to be weak to moderate, and at least a low threat of severe storms may materialize from MN to MI. Should such a trough occur, a strong storm threat could extend into the Northeast as well toward Monday/D8. Otherwise, the weak winds aloft and generally high heights should preclude much potential across the remainder of the CONUS through the period. Read more

SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0225 AM CDT Mon Jun 17 2024 Valid 191200Z - 201200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms are not currently forecast for Wednesday. Portions of the Texas Coast will need to be monitored closely for potential tropical weather influences going forward. ...Synopsis and Discussion... A strong upper ridge will exist over the northeastern states on Wednesday, providing hot weather. This ridge will deflect an upper trough over MN early northward into Ontario and toward Hudson Bay, then eastward into Quebec through Thursday morning. At the surface, a residual front will extend roughly from the upper Great Lakes into the central Plains, providing weak low-level lift. While bouts of rain and thunderstorms are expected throughout the day along this zone, weak shear and warming temperatures aloft preclude any low severe probabilities this far out in time. To the south, an area of disturbed weather currently has a 60% probability of cyclone formation in the next couple days per NHC guidance, and this could potentially enhance low-level shear and potentially affect the TX Coast. If this occurs, low tornado probabilities may be needed in this area in later outlooks. ..Jewell.. 06/17/2024 Read more
