Valid 140100Z - 141200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe-thunderstorm potential appears minimal tonight.

....01z Update...

Leading edge of large-scale forcing for ascent is spreading across
the southern Rockies into the southern High Plains early this
evening. Weak convection, with a few flashes of lightning, has
developed between MAF and LBB. This activity is expected to
gradually increase ahead of the front as mid-level lapse rates
steepen/cool in response to approaching upper trough. Diurnal
heating has contributed to isolated thunderstorms beneath the trough
across portions of the Four-Corners region, but this activity should
gradually wane with loss of heating.

Weak convection remains possible along the Pacific Northwest Coast
tonight within onshore flow regime. Very steep lapse rates and low
freezing levels suggest a few flashes of lightning may occur with
low-topped convection.
