FORECAST:

A weak upper level low in a Southwesterly flow aloft will bring a few showers this am then slowly transition to unsettled weather by this afternoon.  The FL will spike at around 1400 meters dropping back down to 800 meters by tonight. The high will begin to build tonight into Wednesday morning for a nice sunny day on Wednesday. The FL will likely top out at around 1800 meters with day time heating. We may see some convective clouds develop Wednesday afternoon. Thursday is looking unsettled with a mix of sun and cloud. Friday at this time is looking like a nice sunny day. Models are not in agreement for the weekend so more on that as we get closer. Split flow is forecasted so there is a good chance of a weak upper trough pushing through. Guesstimates: 1-3 cm by Wednesday morning.

FORECAST:

Unsettled this am with a mix of sun and cloud before an upper trough in a Southwesterly flow aloft brings overcast skies this afternoon and light precipitation tonight. Will likely see some rain showers this afternoon with the FL rising to almost 2000 meters, then dropping back down to 1200 meters by Tuesday morning. The weak trough will push through by Wednesday morning as a weak ridge builds with mostly sunny skies. The low remains offshore and will likely send some cloud our way for Thursday but without any moisture. The ridge will rebuild for Friday into Saturday. Models are inconsistent so its difficult to determine exactly what will transpire. A series of frontal bands is expected Sunday into Tuesday of next week. Guesstimates: 8-12 cm by Tuesday morning above 1600 meters, trace to 2 cm by Wednesday morning.
