OK, I have been using WXSIM for quite some time now, 99.9% of the time in auto mode. I cant’ seem to get a handle of the optimum time of day or number of forecasts I should be doing each day. The NWS forecasts for the most part always are more accurate than mine. I have scoured the forum for some hints on this and can’t seem to find what I need.
Currently I am doing a forecast just before sunrise and another about 15:00.
Any suggestions???
Many thanks!

I have my WXSim run a forecast every 3 hours from 03:38am (02:38 UTC), except for the midnight one, so that’s 7 runs a day.
When I started I used to run 3 a day, at 04:00, 12:00 and 18:00 but I wanted it updated more often.
Hi Al,
Since you’re so nearby, I think you might want to try more or less what I do: 8 AM, 11 AM, 4 PM, 10 PM (a few minutes after these hours, actually). You might also throw in a 6 AM so you have a fresh one to look at in the morning. It works almost as well any time of day, but mid morning and early evening can be a bit iffy temperature-wise since the temperature is often changing very rapidly at those times. Also, it’s good to have a run made shortly after fresh GFS data becomes available. I haven’t checked lately to see exactly when that is, but I think it’s around 2 AM, 8 AM, 2 PM, and 8 PM EDT.
Hope that helps!
Tom
Thnaks Tom,
I will give this a schedule a try and see how it goes.
I hope you are staying some what cool in this heat wave we are having

Thankfully the AC’s working! Actually WXSIM has been overestimating the highs a bit lately (but nailing the lows). What about in your case?
Tom
Hi Tom,
In my case the highs have been right on and lows not so good
Al
My 2p CST models are very good; highs and lows. I’m still bouncing back from ‘too high’ because I wasn’t using ‘stop am rain’.
I canxd my 10a CST/4p CST/8P CST models as those were way off. Now, my 6a/12p/2p models are starting to improve.
I’ve found the real key to be refinements in the ‘stop am rain’ and only use it when winds ese-sw.
Of course, it will be interesting with the hurricane.
