Cod has had issues before and again this weekend. Even their model's page has been on/off again beginning on Fri. In the past it has happened on weekends and is fixed Mon/Tues.

The last post included fill for below zero surf. temp. It looked a little congested so replaced that fill with purple zero line. #Precip Water and snow lines Erase analyze,sdvc=9:25.4 stor=9 ssum=7:8 stor=8 mixr hsfc stor=7 ssum=3:6 stor=6 ssum=4:5 stor=5 mixr h925 stor=4 mixr h850 stor=3 ssum=1:2 s...

After getting hammered with snow the other snow scripts were a little low. Using PW w/snow lines was more accurate for my area in Central VA.

I hope all previous scripts have been valid (add this one to the list), as always if there is a mistake somewhere let me know. Also working on Snow Squall index, if Tim is checking or anyone else for that matter and can tell me if: analyze,stor=5 grtn=60 relh h850 stor=4 grtn=60 relh hsfc is valid a...

If you save the results over time this script shows increase in temp gradient (frontogenesis) and areas to keep an eye on.

These are EXPERIMENTAL. The Garcia Method of snow forecasting uses ave mixr * 2 to calculate Max snow depth for a forecast area. The first script uses ave. mixr from 500mb to surf and multiplies it by 2 to show max snow level, the "snow lines" for various thickness and surf freezing temp i...
