After early morning fog for some burns off after sunrise, look for warm and dry conditions with highs in the mid-80s. Sunday morning starts out dry with the risk for showers and storms slowly spreading northeastward through the day, becoming widespread by Monday morning. Total rainfall amounts of 1-2 inches are possible for some locales south of I-90 (20-40% chance).
After the rain departs Monday night, the middle of next week is shaping up to be hot and humid. Wednesday looks to be the warmest of this stretch as highs soar well into the 90s and heat indices climb into the 100-110 degree range. An increasing risk for showers and storms later in the week also increases the uncertainty in the temperature forecast for Thu & Fri, with some indications that temperatures could be cooler than currently forecast.
