5/21 – Trey Tonnessen’s “Overnight Warmth” Tuesday Night Forecast

Meteorologist Trey Tonnessen

The forecast for the rest of this workweek doesn’t look to change much. High pressure will maintain hot and rain-free conditions. Temperatures will creep up a few degrees the rest of the forecast period as the upper ridge nearby strengthens. A few locations could approach record highs this weekend. At the moment, it doesn`t appear that dewpoints will be high enough to support heat indices anywhere near heat advisory, but should at least exceed 100 late this week. The ridge will continue to be suppressed southward as another trough tracks across the mid Mississippi River Valley this weekend. That`ll eventually allow for some afternoon convection but currently doesn`t look like that`ll happen until sometime next week.
