Weather Briefing, EC model forecasting precip Wed-Thu from short wave upper level trough passing over the ridge, BUT north of our area. GFS still dry (though wetter than previous runs) but all precip north of SF Bay Area. Bottom line, no TO/Landing issues. BUT, the short wave trough will produce a band of mid-level moisture (in the “icing temperature” range) coming across Wednesday about 12Z (landing time). Icing is highly doubtful in my opinion, but USAF forecasters may forecast it. We have had this scenario before. Bullet 2 is the only ops weather issue next week. Wx still looks good for late Thursday takeoff (or early Thursday).

4 AM Wednesday get enhanced probability of mid-cloud over our area. Sounding is moist in the -25 to -35 region, so USAF forecasters may predict icing. These are GFS soundings. If the more active, wetter EC model verifies, this will look worse.

These are the relevant forecast Times for ghost viewing for BOTH Takeoff times (10 AM Tuesday to the right, 4 PM Tuesday above.) New forecast suggests that heading west is as good or better than heading east (subject to SZA).
