9/25/2019 – Nice day! MAYBE a shower tomorrow and a bit more humid. I am showing a chance of a storm Saturday – will be HOT that day. Possible heatwave next week – I went 88 on Tuesday (bit higher than the NWS) but may need to go to 90 if trends continue. SOME indications of a change in patterns late next week. Not holding my breath yet.. pattern change would bring in some cooler air. Have a great Wednesday!
