Don’t get too comfortable with the brief early glimpse of fall that we experienced over the past weekend, where morning temperatures fell into the 50s and lower 60s across the forecast area on Sunday coupled with a dramatic decrease in humidity levels. Winds will abruptly and vigorously turn back to the south in response to a deepening low pressure system ejecting out of the Rockies onto the Northern Plains. This system will have little impact on our sensible weather, but the increase in southerly wind speeds will advect Gulf moisture back into the area. As temperatures warm back to and above seasonal normal values (89°F normal high for this time of year), heat index values will also soar back to above the century mark by the end of the week, thanks to the increase in humidity. A weak cold front will approach the area by the end of the week with perhaps a few spotty showers and thunderstorms along the Red River. This will be something to watch because if the front sinks farther south, then our chances locally increase for isolated showers and thunderstorms. Though the summer heat will try to make a valiant comeback, at this time, there does not appear to be any sign, aside from the heat index, of triple digit ambient air temperatures. Not too much longer to go before it will be impossible for triple digit heat to occur until next year. Thus, the clock is really winding down fast on summer…
