1PM Day 1 Convective Outlook for Monday, January 26. NO THUNDERSTORM AREAS FORECAST
SUMMARY
No thunderstorms are expected.
Discussion
Occasional lightning occurred earlier today near the Florida coast with a weak line of storms that developed along the cold front. This convective line has weakened/moved far enough offshore to bring an end to any thunder potential across Florida. A dry, continental-polar airmass, which has now become established across much of the CONUS, will continue to limit any thunderstorm potential.
Discussion including South Florida
Longwave trough will remain prevalent east of the Rockies, with some late-day amplification of the upper ridge into the West in advance of an approaching shortwave trough. High pressure and cold/continental trajectories will extensively prevail east of the Rockies, with an exception being ahead of a cold front crossing the Florida Peninsula. While near-frontal convergence will remain weak, and mid-level lapse rates are poor, additional boundary layer warming and deepening convection may be conducive for a few lightning flashes, mainly near parts of the coastal southeast Florida Peninsula through afternoon.
