A slowly building weak ridge of high pressure will eventually bring warm dry weather to our zone. Low level marine cloud has made its way inland with onshore low level flow and a Northwesterly flow aloft. The FL will rise to 2400+ meters and there is a slight chance of some rain showers this afternoon. Unsettled conditions will prevail into Friday & Saturday with a mix of sun and cloud before the ridge strengthens by Sunday with warmer temperatures and sunny weather.
Guesstimates: trace -1 mm by Friday morning. Trace-2 mm by Saturday morning. The air mass is dry so little chance of any precipitation.
