The temperature soared to 101 degrees in downtown Baltimore yesterday, tying a record that was set in 1940, said Dick Diener, a National Weather Service forecaster.
"The humidity has dropped significantly, so we won't have another heat wave, just a few days of warm weather," Mr. Diener said.
The high temperature reached 94 degrees at the Baltimore-Washington International Airport -- four degrees below the record of 98 set in 1955.
While today's downtown temperatures are expected to be in the low- to mid-90s, it is "conceivable we will hit the 100s again," said Mr. Diener.
It will be partly sunny and humid tomorrow with a chance of showers and thunderstorms.
"The rainfall is still below normal. The city and airport still need about two inches of rain to catch up to the normal of [more than three inches for July]," said Mr. Diener.
So far this month, the rainfall has totaled 1.77 inches, and most of it fell on just three days -- July 2, 6 and 14.
"We need several days of a general rainfall to help the farmers," he said, adding that the rain that's been falling on the Midwest will shift beginning Friday throughout the southern and eastern parts of the country.
The Baltimore area can expect cloudy weather with cooler temperatures, in the 80s, over the weekend, he said.
