FORECAST:

Unsettled again today with mostly cloudy skies this am but more breaks as the day prgresses. Still a chance of some isolated showers but after what happened yesterday perhaps not!! An Easterly flow aloft this am will transition into a Southeast flow aloft by this evening. The FL will remain well above the local peaks. Ridge strengthens on Wednesday pushing more inland and will remain until Thursday. Chance of some cloud development on both days. A trough is forecasted to arrive Thursday night into Friday with some needed precipitation. The ridge rebounds again for Saturday with unsettled weather becoming sunnier for Sunday. Still cannot believe with the clouds we had yesterday it did not rain more!!!
Guesstimates: Nil to a trace by Wednesday morning.
