Today will be the last day of the recent record-breaking heat wave, as the upper-level ridge will finally begin to weaken this afternoon. Unfortunately, this means another day of record or near-record temperatures for most of the state. As shown in the visible satellite image, below, the ridge is centered over southwest Colorado this morning and has weakened slightly over the past 24 hours. Some monsoonal-type mid and high-level moisture has found its way around the northern periphery of the ridge this morning. Grand Junction’s PW<\/span> has increased from 0.48 to 0.58 inches over the past 24 hours with most of the increase coming in the mid and upper-levels. Nonetheless, this will support a slight increase in storm coverage west of the Continental Divide<\/span>, although only light precipitation is expected there today. East of the Continental Divide<\/span>, dewpoint temperatures have generally dropped by 2-4F since yesterday morning. Denver’s PW<\/span> is up slightly from 0.49 to 0.54 inches this morning driven mainly by increases above the boundary layer<\/span>. Boundary layer<\/span> moisture continues to be very shallow, and slight drying since yesterday, especially along the KS\/NE border, suggests a reduction in storm coverage and peak rainfall intensity today.<\/p>\n Overall, we expect another round of isolated<\/span> to widely scattered<\/span> shower and thunderstorm activity mainly limited to the higher terrain as well as the Southeast and Northeast Plains. Weak steering flow and marginal instability implies storms will have a hard time staying intact for more than 30 minutes. Pulses of moderate rainfall are expected today, but there is no flood threat. Isolated<\/span> large hail will also be possible with the strongest storms in the eastern plains.<\/p>\n![\"\"](\"https:\/\/archive-coftb.dewberryanalytics.com\/wp-content\/uploads\/2021\/06\/vis_markup-5.png\")
