90 DEGREE HEAT STICKS THROUGH MONDAY AND TUESDAY
DAILY SHOT OF RAIN THIS WEEK
POCKETS OF HEAVY RAIN POSSIBLE AT TIMES

Most of the area has reached or surpassed 90° for nine straight days, including Sunday. As a result, this is one of the hottest summers on record so far for the area.
The 90° heat continues on Monday, at least for the Tri-Cities and surrounding valleys. Most higher elevations will be in the middle to upper 80s. As a weak front moves towards the region, a few storms may spark ahead of it - favoring the higher terrain Monday afternoon and Tuesday afternoon first before drifting into the valleys. Brief downpours, lightning and even some hail in spots are possible. Keep in mind that there will be a good deal of dry time each day. Don't expect it to be raining all day. The rainiest times will be in the late afternoon or evening.
This aforementioned front will stall along or just north of the Tri-Cities, and will serve as a boundary for a storm system to ride along later in the week. As this storm system draws in more moisture, we'll notice temperatures returning to more seasonable levels due to cloud cover and rain chances increasing (mainly Thursday through Saturday). Pockets of heavy rain will be possible. Stay tuned, as we continue to fine-tune the forecast on our end.
Temperature Outlook: Highs in the 90s Monday, at or near 90 Tuesday, and mid to upper 80s the rest of the week. Lows in the upper 60s to low 70s all week.
Our average high is 85°, low 64°.
