Widespread Rains

Showers on Catalinas and foothills at 6 pm MST yesterday afternoon.


There were widespread rain reports across the ALERT Network yesterday (above and below) for 24-hours ending at 7 am this morning. A couple of the null reports look a bit suspect. Here at the house we had 0.31"; the airport had 0.23"; DM AFB reported 0.32"; and Atmo had 0.16". This was first significant rain here since March 10th.



The 09 UTC SREF plumes for QPF at TUS (above - from SPC webpage) show several  members indicating very light amounts after 12 UTC at the airport, but with a few showing over a quarter on an inch. The current morning forecast from the NWS for the airport (below) indicates slight chances for showers and thunder today. We shall see.

    Bob, what were the factors that created such an interesting rain event on 5/4?

  2. Hello - obviously I haven't been paying much attention during this very quiet month! There was a flat ridge just to our east,
    and a weak shortwave crossed by in the evening. as the large, closed-low off California moved eastward. I can't seem to
    insert the analysis here, but it can be called up at the SPC web site.
