"CUTOFF" LOW LINGERS
Circulation around low pressure in the northern hemisphere is counter clockwise and full evident in visible satellite imagery Thursday afternoon The low anchored over central Indiana continues to churn clouds and carry a shower with it.
Late in the day, more organized showers are 'backing' (moving east to west) in from Ohio, rare for weather here to move from east to west. The prevailing upper level winds run from west to east, but they have cut off this low and it's been dropped our lap for a few more days.
The unsettled pattern will continue though Saturday when improvements will be fully underway. Cool and showery weather is expected to continue Friday. The high temperatures were officially held int the 60s again Thursday for the second straight day, firt time with back to back highs since mid May.
WARM SEPTEMBER HANGS ON
Despite the recent cool off the average temperature since September first is the warmest in 75 years! Nearly 70% of the days have been above normal and currently September and the start to meteorological fall ranks 10th warmest on record. That among the warmest 7% on record, dating back 145 years. The average temperature is currently 5° per day above normal
The upper low will weaken then departing starting this weekend. Shower chances will not be completely ruiled out for Saturday but coverage should be minimal. The low will finally get scooped up by upper level winds by Sunday, that's when the weather should really take a turn.
Wioth added sunshine, high temperature climb into the 70s Sunday and will likely warm to near 80° by Tuesday and Wednesday.
