Overall buoyancy will be meager, but robust vertical shear could still support a strong storm or two. Thunderstorms are also expected throughout the day across northern and central CA, where strong forcing for ascent will interact with a moist and modest buoyant air mass. Limited moisture should temper thunderstorm coverage. A few thunderstorms are also possible during the morning from the TX Panhandle into central TX as the southern-stream shortwave trough moves through. Some isolated thunderstorms are possible in these areas amid modest ascent attendant to a weakening front. Surface pattern early in the period east of the Rockies will be dominated by high pressure, with the low-level moisture shunted south into Deep South TX and the FL Keys. Farther west, a low-amplitude southern-stream shortwave trough is expected to move quickly through the southern Plains into the Lower MS Valley and another shortwave trough will move through northern/central CA into the Great Basin. This cyclone is then forecast to progress northeastward off the Northeast/New England coast as shortwave ridging moves from the northern/central Plains eastward through the Mid/Upper MS Valley into the Lower Great Lakes. SynopsisĪ mature mid-latitude cyclone will likely be centered over PA early Tuesday morning. Severe thunderstorms are not forecast on Tuesday.

This trend will continue this evening as the front advances south. Scattered pre frontal convection is sagging south across this region, but is becoming less concentrated over land. 00z sounding from MFL verifies this with 850mb flow now westerly at 25kt. Westerly flow is deepening across the southern FL Peninsula this evening. Severe thunderstorms are not forecast tonight.
