.DISCUSSION... Largely dry conditions expected around the forecast point
Friday as surface high pressure influences keep cloud cover scattered
at best. Big things to watch will be a light northerly to northeasterly
wind set to shift more easterly as lake breeze processes commence by the
afternoon. Initial drier conditions with RHs in the 30s and 40s may become
less dry as the marine layer advects inland and dewpoints rise a little.
Expecting surface temperatures in the mid-upper 50s to near 60, potentially
cooling a few degrees as the lake breeze forces its way inland.
