(OLNEY/NEWTON) As a surface high pressure ridge axis has slipped to the east of us, a southerly wind flow will continue to pump in hot and humid air into the Midwest. As a result, our downstate area heat index values will be the highest so far this year and with the airmass becoming unstable there is the slight chance of an isolated shower or pop-up thunderstorm late this afternoon and/or evening. Then we’re back to hot and humid conditions tomorrow and Monday. As of right now, our next significant chance of rain is a low pressure system and cold front that’s expected to move through by next Tuesday night or Wednesday, however some weather models are struggling with that airmass shift next week. Stay tuned to Freedom 92.9 and to a NOAA Weather Alert Radio for continued weather updates and/or any possible warnings or alerts.
