On Wednesday, with a high pressure system to our southeast and a warm front well to our north, the southerly flow will be in full swing. Decent heating will take place and temperatures should climb well into the nineties. With dew points in the mid to upper sixties, with some isolated lower seventies, heat index values should climb to about 100 degrees with values as high as 105 degrees in the hotter, urbanized settings. The same should be repeated for Thursday.
Thunderstorms on Wednesday should be very isolated, but any rogue storm could be quite strong in the heat and humidity. On Thursday, the timing of the front has been moved up, and that means some showers and thunderstorms may develop towards evening and night. If these move in after 8 o’clock, we may dodge a widespread outbreak of severe weather. However, one or two strong thunderstorms are still possible. On Friday, the front should be pushing offshore and some drying should occur in the afternoon and evening. This frontal timing may change again, so keep us on the bookmarks and check back with us throughout the week.
