Another week in the 90s ahead

Forecasters are calling for another week of ... well, July weather ahead. They're expecting some showers and thunderstorms Monday and Monday night as a "cold" front pushes through. It's really more of a less-hot front. But after last week's foray into the 100s, it sound just fine to me.

Forecast highs will start the week in the low 90s, with somewhat drier air (dew points in the 50s and Summer shower60s), and gradually push into the mid-90s, with sunny skies and rising humidity, as the week rolls by. The average highs for BWI at this time of year are closer to 87 degrees, so we remain on the hot side. But no one seems to be looking for more triple-digit weather for now.

Any storms we see today and tonight are not likely to become severe. But with so much moisture in the atmosphere, we could be looking at some heavy downpours from slow-moving thunderstorms, forecasters said. Rain chances are put at 70 percent this afternoon and 60 percent tonight.

Once the front goes by, we can look forward to overnight lows dropping into the much more comfortable 60s for the next two nights (70s downtown). We may even be able to open the windows as listen to the cicadas.

As the high begins to move off the coast late in the week, daytime temperatures will climb back into the mid-90s, with rising humidity. We will likely be talking about Heat Advisories and the Heat Index again by Thursday or Friday, as the numbers poke back into the low-100s.

The next break is likely with a new cold front on Sunday.
