Time

We have an upper level high pressure ridge moving through the area this evening which gave us a dry day today but the ridge continues to push eastward as we see a harsh low to the east. west approaching while a low pressure area also moves southeastward towards the area, and the combination will bring rain to the area tonight around midnight. Winds overnight from the south 4-8, low near 49.

It looks like the trough will stall and provide a path for a series of systems to bring rain to the area, so tomorrow looks cloudy and rainy, winds still southerly 4-8, highs near 55. Rain continues tomorrow evening then easing some after about midnight, winds calm, lows near 44, total precipitation less than an inch.

On Saturday the flow flattens out or becomes more zonal, west to east, and that reduces the chance of rain, so I think we could see a few brief spells of light rain or drizzle, especially in the morning with some scattered fog. Winds shift back to the southerly 4 to 8, and the high rises near 57. The southwesterly flow returns late Saturday evening through early Sunday morning, so the chance of rain is starting to increase, reaching near lows. of 44.

On Sunday morning, a large upper level trough returns to the area and brings rain which persists at least through the middle of next week as the trough slowly dips southeastward. While high temperatures are in the mid-50s for the start of the week, they drop into the low 50s through Wednesday. The lows also drop into the upper 30s.
