.KEY MESSAGES...

1.Warming trend Wednesday into the weekend with high confidence

of at least Moderate Heat Risk in the Valley Sunday through

Tuesday.

.DISCUSSION...



The cutoff low that brought cooler temperatures on Monday and

Tuesday is moving off to the east. A ridge of high pressure

slides in overnight into Wednesday morning and will strengthen

into the weekend. The ridge will bring a strong warming trend.

However, the heating trend brings high confidence of a Moderate

Heat Risk for Sunday through Tuesday including Fresno's 75th

percentile high temperatures being around 105 degrees on Monday

and Tuesday. 



This ridge of high pressure also keeps winds to be light and

diurnal especially for the foothills. However, the mean minimum

Relative Humidity values drop to the low teens in the Valley and 

in the high teens to low 20s for the Foothills and Sierra Nevada

by Tuesday. The CPC has the area under a 80 to 90 percent chance

of above average temperatures in the 6-10 day outlook. The 8-14

day outlook suggests a pattern change with a 33 to 40 percent 

chance of above average precipitation, however, that would be

anything above a trace in the Valley for mid-May. The 8-14 day

outlook also has a 50 to 60 percent chance of above average 

temperatures.
