im not sure people here read everything or just skim... perhaps my communication skills are weak -- im talking about the "radar hole" west of I95 and have been the whole time.

There is a min in the Dulles area. They have 0.6", and several of the surrounding sites - Ashburn, Centerville, etc. - are near that amount. I'm at 1.07" near the western Beltway, so the radar estimates are quite low.

yeah they're often wrong but they still show the general pattern.

Culpepper schools closing early? Over rain?

that's just west of me. we got bombed with the sunday storm...2.5 to 2.8" widespread from CHO to Louisa to Culpepper.

as of yesterday morn there were still streams flowing across roads.

we dodged a bullet last night though compared to fred'burg and easty areas and that trend continued throughout today. in light of that, it does seem odd but it won't take much more liquid for bus drivers to not want to chance water crossings with fast flowing streams.

seems over reactions abound these days though.
