SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1159 PM CST Wed Feb 14 2018 Valid 161200Z - 171200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Potential for thunderstorms is low across the continental United States on Friday. ...Synopsis... Broad upper troughing in place at the beginning of the period is expected to persist as one shortwave trough moves through the Upper Great Lakes, OH Valley, and Northeast and a second shortwave moves across the northern/central Rockies into the northern/central Plains. At the surface, a cold front is expected to extend from southern New England southwestward all the way to the TX South Plains at 12Z Friday before progressing steadily southeastward/southward throughout the day. This front will likely stall near the end of the period and will likely stretch from the middle TX coast into central GA at 12Z Saturday. An anonymously moist airmass will exist ahead of this front but warm temperatures aloft will prevent deep convection and resulting lightning production. Elsewhere, an isolated strike or two is possible across portions of west/central TX as a low-amplitude, fast-moving shortwave trough moves across the region Friday evening and overnight. However, like areas farther east, warm temperatures aloft are expected to limit updraft depth and lightning production, keeping thunderstorm coverage less than 10%. ..Mosier.. 02/15/2018 Read more
