This evening’s latest models continue with the trend that was showing earlier in the day — The low pressure system that had been expected to give us rain all day Saturday now appears to be on a much faster track. Rain will likely end early to mid morning on Saturday! (Some models have it ending as early as 7 AM, some by 10 or 11 AM Saturday.)

Rain will start earlier, now during the morning hours Friday and will increase during the afternoon and night time hours Friday.

Here’s the latest NAM-NEST model showing rain departing to the east at 7 AM Saturday—

It’s uncommon for the 48 hour forecast to be so uncertain.  The models have been all over the map regarding the development, track and speed of the low pressure system that will affect us on Saturday.

Even the NWS Weather Prediction Center meteorologist seems frustrated by the models—

“Through the 12Z/18Z guidance, ongoing saga of model disappointment continued, owing to a rather unpredictable shortwave pattern amid a mostly predictable longwave pattern.”

That said, here’s the latest forecast based on this morning’s models— It appears that the storm will be moving faster and further east than previously forecast. (which I alluded to last night.)

The rain will start earlier Friday afternoon and will end earlier on Saturday, probably just after noontime Saturday. No snow or flurries in this forecast.

(Previous forecasts had the rain lasting into Saturday night or Sunday morning with snow flurries at the end.)

Stay tuned for updates.
