Poor Model Forecast

It was supposed to be a dry frontal passage this morning, but that hasn’t panned out.   The models show as little as a 4% chance of showers this morning, but the short range models (GFS-LAMP) have increased the chances s bit.  Nonetheless, radar shows that an area of fast-moving showers is passing through.

Interestingly, the NAM model was updated and enhanced this past Tuesday, but I see little improvement in the precipitation forecasts since then.

For the balance of the day, broken clouds, showers early morning , then clearing in the mid-afternoon.

The NAM model has again over-estimated the precipitation for this weekend and the GFS has backed off on the heavy rains as well.
