- A nice day today, but with a slight chance for a shower in the mid to late afternoon with the best chance being along and north of the Expressway.
- Tomorrow looks even better with high clouds arriving in the late afternoon.
- Rain mainly arrives around early to mid morning on Friday and continues into the evening/night. There may be a break at times Friday night with the rain possibly ending Saturday afternoon, but there is uncertainty.
- With a strong pressure gradient behind the storm, Sunday will be windy with gusts possibly up to 35 mph!
- Really chilly air then arrives Sunday night into early next week with some cold nights!
- Next week looks basically dry with milder temperatures for mid to late week. Eventually a strong cold front will come through with some showers, but not sure if it will be Saturday or Sunday. Either way, it looks very chilly for Halloween.
- Invest 94L should finally become a Tropical Depression around tomorrow or so and probably Tropical Storm Tammy as it heads towards the northeastern Caribbean and then curves northward.
- The rainfall maps below are from the Model Blend, Weather Prediction Center, Euro, and Euro ensemble mean.
- I will probably post a timing video this morning for the rain from the new 06Z Euro when it comes out.
