Despite the very wet Monday, going into Tuesday, we will begin to see drier air move in as high pressure builds. After a cooler than average day today, and a near average Wednesday, temperatures will begin to warm above normal late week, through the weekend, and into next week. As this happens, we will see daily reductions in storms and rain amounts.
We are sitting under deep monsoon moisture NOW...but the pattern over the next several days will transition to high pressure parked over the region. This will allow for warming, with temperatures back above normal. In addition, the high pressure feature will interrupt the moisture feed into the area, with dry air working in. This will significantly reduce the chances for showers and thunderstorms, with a lot less rain across the region.
Drier and warmer air will slowly filter into the region over the next few days. High temperatures for the weekend into the first of next week, will be near or a little above 100°F for most lowland locations. The heat looks to continue into the middle part of next week.
Temperatures climb to 5-10 degrees above normal early next week with moderate to major risk of heat-related impacts Monday and Tuesday.
