Forecast Discussion:

Tabulated winds Monday were pretty impressive (nothing reported above 90 mph as some said was possible - Figure 1). Our story today is: yes, warm dry weather continues. High pressure is back in control today (Figure 2) with fading winds.

The next three days (snapshots just after sunset) will be 8-12 degrees above normal - Figures 3, 4 and 5. Pretty straight forward. But wait! What's that in the longer range forecast below?

The longer range forecast:

A new (not very major) storm has appeared in the model data (the GFS - Figure 6) and at weatherunderground.com's model. That storm, if it materializes, will cool us to near normal temperatures again (lower 40's F) and bring a chance of rain. We'll keep an eye on it!!
