Strong Wind and What is in the Sky?

April 21, 2015

Another very windy day. Peak wind gusts today in the 40-50 mph range.

Peak Wind Gust - 4 Lines

The wind remains breezy tonight and as the sun comes up Wednesday the wind will increase again. Wind gusts most of tomorrow will be closer to 30 or 35 mph. The sun sets Wednesday and the wind diminishes quickly. By Thursday morning a frost or freeze is possible for a few hours. The wind forecast below shows the wind remaining from the northwest through Wednesday night.

The clouds we had today are slowly clearing out. Here is a visible satellite image from this evening.

2

The clear sky will give us a chance to see a few things this evening. First if you look west you can see Venus and the Moon. (Waxing Crescent with 12% of the Moon’s visible disk illuminated).

The other thing is the International Space Station. It will be visible at 8:51 pm for 4 minutes…traveling from the W to SSE.
