October 24, 4:30 PM Weather Forecast Update

Here is a look to Halloween & even as far as Post-Thanksgiving, based on the latest data this afternoon.

After upper 20s to mid 30s this morning & around 50 to the lower 50s today, we will drop to around 30 area-wide tonight.

High clouds will gradually increase & then thicken throughout tomorrow morning.  By afternoon, it will turn mostly cloudy to cloudy with virga (rainfall that completely dries up on the way down).  Highs will run near 50 to the lower 50s with east-northeast winds at 10-20 mph.

After 36-40 tomorrow night, highs Friday will run in the upper 40s to around 50.  A gray day, there may be a few isolated showers in the morning, but a large area of showers should overspread the area in the afternoon & last into the evening.  These do not look heavy.  Final rainfall amount by late Friday night will run 0.02-0.20" with the highest amounts in the southern part of the viewing area & the lowest amounts in the north.

Saturday looks a bit gray, but with only a couple isolated showers possible & 50s, it will not be too bad.

Sunday looks wetter of the two days with showers developing & cooler highs in the upper 40s to the lower 50s with windy conditions.  At this point, the peak rainfall coverage should be in the afternoon-evening.

Monday will feature only isolated showers.

Tuesday looks nice!  With lots of sunshine & a lack of wind, highs should run 55-60.

Winds should increase Wednesday to gusts of 20-30 mph from the south to southwest.  Clouds will be on the increase.  Some showers are possible late.  It is unclear how early they will get in, but they could impact the very end of Trick-or-Treating.  That is the current thinking, but that may change.

Once the Halloween system moves through with rainfall Wednesday late to Thursday, the pattern should remain active through early November with multiple storm systems coming through.

It will also become increasingly warm with temperature above normal, but count on a lot of wind.

Note the big trough in the West & ridging in the Southeast signaling warmth.  Also note that we are in the zone of multiple troughs & jet streams right to mid-November, indicating active weather with rain & storms frequently.

Also, notice how the pattern chanages after mid-November & that we get into troughiness.  This signals much colder weather.  Some minor snowfall could even occur between mid-month & Thanksgiving.

After the deep trough with perhaps minor snowfall just before Thanksgiving, note how the flow becomes more zonal after that.  This signals milder Pacific airmass bathing our area.  It also will dry us out after above normal precipitation for a good chunk of November.
