FORECAST:

The ridge is forecasted to shift Eastward today with a cooler marine push in a light Southerly flow aloft switching to Southwesterly later today. We may see some cloud development later in the day but there is a chance it may stay South of our zone. The FL is supposed to drop to around 3000 meters later today. There are some discrepancies in the various models, but it looks like we may see some unsettled weather Thursday through Sunday. Good chance the ridge will rebuild for Monday. Weak weather disturbances may bring the occasional shower but it will all depend on what the trough coming from the South does, possibility it may stay Southeast of this area. Slight chance of some lightning & thunder, likely will stay to our South.
Guesstimates: trace-3 mm by Thursday morning, trace-6 mm by Friday morning, trace-5 mm by Saturday morning, trace-8 mm by Sunday morning, trace-1mm by Monday morning.

Please note there will be a VERY LARGE group heading up to the Wendy Thompson Hut this coming long weekend and we have rented the entire hut and will have folks tenting outside as well. Just want to give you all a heads up so that you don't expect peace and quiet if you're headed that way.
Happy May long!
