However, a strong, 500 mb short wave digging south from Great Basin (analysis above for 12 UTC this morning from SPC) promises a return to unsettled weather, especially the next couple of days. The 500 mb forecast below is from the 12 UTC NAM this morning - that model forecasts the resultant closed low to be over Arizona tomorrow at 12 UTC.
The forecast from this morning's WRF-RR (bottom, radar valid at 4:30 pm MST this afternoon) indicates a chance for showers and thunderstorms over eastern Pima County beginning late afternoon today and then continuing chances through tomorrow.
