Dry high pressure will be the main weather feature today and into Saturday as well. Excellent mixing will keep dispersions in a fair range despite low level winds generally below 10 mph today, but this will also result in MinRH values below 30% during the afternoon and evening. Saturday, flow shifts around towards the west to southwest and picks up a bit as well, increasing RH values slightly but dispersion as well with good to borderline high dispersions expected. .REST OF TODAY...
