Amounts from other forecast models for after-the-fact verification: NBM: 0.79”, Euro: 1.72”, Euro ensemble: 1.36”, GFS: 1.02”, GFS ensemble: 1.56”, Canadian ensemble: 0.77”.
Tuesday through Sunday… Moisture and instability will decrease giving us just a slight chance for isolated showers and a thunderstorm or two each afternoon into each evening. However, some forecast models keep us dry Thursday through the weekend, so my forecast confidence is decreasing for precip during this period.
Winds… Afternoon gusts will be 15-20mph, but isolated stronger gusts are possible near showers and thunderstorms.
Temps… Highs will be in the high 70s to mid-80s and lows will be in the mid-40s to low 50s.
