Hit Or Miss Thunderstorms

Yesterday featured scattered, hit or miss, thunderstorms, which matched the basically inert large-scale environment. Detected CG flashes shown above for 24-hours ending at midnight last night. Character of the rainfall was also indicated by the metro-west sector of the ALERT network (below) for 24-hours ending at 6:00 am MST this morning. Across the entire network about 60% of the sites measured rainfall. Here at house, an early afternoon shower produced 0.06".

Little change this morning, except that the wind directions are trending toward the west and drier air is encroaching from that direction. The 06Z WRF model forecasts from Atmo show that NAM version indicates a similar day today, while GFS version has less activity.

In the longer term, the NHC tropical outlook (bottom) indicates that the remnants of Hurricane Earl may re-develop once they move across southern Mexico.
