FORECAST:

The ridge continues to bring sunny warm conditions in a Southerly-Southeasterly flow aloft. The FL will be above 3000 meters and we may see another day of record breaking temperatures. Onshore flow starts tomorrow with a change in the pattern, clouds will move in late tomorrow afternoon as a few weak frontal bands push through Friday and Saturday with seasonable temperatures. Still hard to put amounts on the precipitation but looks to be minimal. Back to unsettled weather for Sunday into Monday before the warm ridge rebuilds for next week. Guesstimates Trace-1 cm by Saturday morning, trace-2 cm by Sunday morning, better idea on amounts tomorrow.
