The airmass will continue to moisten through the short term period and with the ridge to the west of the region weakening, expect rain chances to increase throughout the weekend. Model guidance for the last couple of days has shown a weak disturbance approaching from the NE on Saturday afternoon and sparking fairly widespread coverage of showers and thunderstorms particularly across our northern zones. Have the higher rain chances tomorrow in our northern zones and lower down near the coast. Given that storms should initiate a little later in the day, will keep high temps fairly warm, in the low to mid 90s. With the ridge continuing to slowly weaken and the airmass much more moist by Sunday, expect an active. This will hold max temperatures back a little, generally in the lower 90s.
Lower pressure will dominate going into the long term as a trough over eastern CONUS replaces the high pressure over the region. This and the return of deep layer moisture will result in higher than average rain chances for the early portion of the week. Mid-week through the end of the period, the GFS and the ECMWF show a frontal system passing through with the tail-end lingering in our area. If these solutions verify, the area can expect widespread showers and heavy rainfall throughout the week. High temperatures will be mostly limited to the upper 80s, barely reaching the 90s.
