Saturday Strong Wind Potential Discussion And OBS


bluewave

Recommended Posts

The models are forecasting a very strong NW LLJ to develop over the region tomorrow 

in response to the tightening gradient behind the surface low to our NE. The forecast

soundings indicate that low level lapse rates are going to steepen during the heating

of the day as a cold pocket moves overhead with the closed low. If the mixed layer

is deep enough during the day, then we could see some wind gusts above the current 

model guidance. The NAM soundings indicate that there could be a very deep 

mixed layer with the potential for some elevated instability. Some trees in full leaf could

come down in areas with saturated soils from the recent heavy rains.
