## Records fall at all three airports

Summer-like air pushed the Washington region to record highs on Wednesday, October 14. The National Weather Service's Baltimore/Washington office said Ronald Reagan Washington National Airport reached 90 degrees, breaking the date's previous record of 87 degrees set in 1975. Washington's official temperature records go back to January 1872. [1](https://forecast.weather.gov/product.php?site=NWS&issuedby=DCA&product=RER&format=txt&version=1&glossary=0)

Baltimore-Washington International Thurgood Marshall Airport hit 88 degrees, two degrees above its 1975 record of 86, according to a separate NWS record event report. Washington Dulles International Airport reached 89 degrees, beating the 86-degree mark from 1975, and tied its record warm low of 63 degrees for the date, a record first set in 2014.

All three reports are preliminary. The weather service says climate data are not final until the National Centers for Environmental Information reviews them.

## A sharp swing across the East

The record day sits in the middle of a sharp swing. Forecasters had already flagged Wednesday's highs as a challenge to the 1975 record, while also warning that frost could follow within days. Thursday brings a cooler, showery day, with another warm-up and storms due Friday.

The same pattern is drawing attention elsewhere. In Louisville, the weather service recorded 90 degrees on October 13, breaking a record of 88 degrees that had stood since 1897. In Southern New England, WHDH said highs on October 14 ran more than 10 degrees above average before cooler, drier air moved in, with Saturday highs forecast only in the upper 40s.

## Friday's cold front and storm risk

In its Thursday morning forecast discussion, the NWS office in Sterling said a weak front would keep the region in the 60s with light showers on Thursday. Sunshine and southwest winds are then expected to push highs back into the low to mid 80s on Friday ahead of a stronger cold front. [4](https://forecast.weather.gov/product.php?site=NWS&issuedby=LWX&product=AFD&format=txt&version=1&glossary=0)

That front is forecast to bring a line of showers and thunderstorms late Friday afternoon into the evening. The weather service said damaging wind gusts are the main threat and a brief tornado is possible. The Storm Prediction Center placed the northern Shenandoah Valley to northern Maryland under a slight risk of severe weather, with a marginal risk for the rest of the area.

CBS News Baltimore named Friday and Saturday First Alert Weather Days. Its meteorologists said Friday's highs in the lower 80s would drop into the 40s and 50s overnight once the rain clears, and that Saturday would bring gusts of 25 to 40 mph, with wind chills in the upper 30s to lower 40s early in the day for the Baltimore Running Festival.

## First frost of the season

Behind the front, the NWS expects highs only in the mid to upper 50s on Saturday, unusually cool for mid-October. Clear skies, dry air and lighter winds Saturday night should allow temperatures to fall quickly. The office said lows could reach or drop below freezing west of the Blue Ridge on Saturday and Sunday nights, and that most of the region could see frost, especially west of Interstate 95.

CBS News Baltimore described Sunday morning as a chance for the first widespread frost of the season, with highs back in the mid to upper 50s and much less wind. A Hoodline summary of the NWS forecast put Saturday night's low in Washington near 39 degrees.

For context, the weather service said the mountains typically see their first freeze around October 11, the Shenandoah Valley around October 21 and areas east of the Blue Ridge around November 1. High pressure is expected to keep conditions dry and calm into the middle of next week.
