NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
232 PM EDT SAT APR 18 2026
DISCUSSION
A COLD FRONT APPROACHING THE APPALACHIANS WILL CROSS THE MID-
ATLANTIC TONIGHT, THEN MOVE OFFSHORE SUNDAY MORNING. A SECONDARY
COLD FRONT WILL FOLLOW IN ITS WAKE SUNDAY NIGHT INTO MONDAY
MORNING. HIGH PRESSURE WILL BUILD IN BEHIND THESE FRONTS LATE
MONDAY THROUGH TUESDAY. ANOTHER FRONT LOOKS TO DROP IN FROM THE
NORTH WEDNESDAY, THEN CROSSES BY THURSDAY BEFORE RETURNING NORTH
LATE IN THE WEEK.
WHILE SOME RAIN IS EXPECTED LATE THIS EVENING INTO SUNDAY
MORNING, AMOUNTS OF A TENTH TO TWO TENTHS ON AVERAGE WILL NOT BE
SUFFICIENT TO WET FUELS SIGNIFICANTLY. IT SHOULD BE NOTED SOME HI-
RES GUIDANCE DOES HAVE LOCALIZED AMOUNTS NEAR A HALF AN INCH, BUT
PINPOINTING THE EXACT LOCATIONS OF THESE SPOTTY AMOUNTS IS VERY
DIFFICULT. STRONG GUSTY WINDS OF 35 MPH WITH POTENTIAL FOR GUSTS
AS HIGH AS 45 MPH WILL CREATE RENEWED FIRE WEATHER CONCERNS
DESPITE MARGINAL HUMIDITIES AND THE OVERALL LIGHT RAINFALL SUNDAY
INTO MONDAY. GIVEN THE SHORT DURATION OF PRECIPITATION (6 HOURS OR
LESS FOR MOST), THE 100-HOUR FUEL MOISTURE VALUES AREN'T LIKELY
TO RISE MUCH AT ALL. THE 10-HOUR FUEL MOISTURE LIKELY RISES
CONSIDERABLY, BUT DROPS QUICKLY THROUGH THE DAY SUNDAY DUE TO THE
DRYING EFFECTS OF STRONG WINDS AND RAPIDLY LOWERING HUMIDITY
ESPECIALLY WEST OF THE BLUE RIDGE AND CATOCTIN MOUNTAINS.
MUCH COOLER TEMPERATURES ARE EXPECTED MONDAY AND TUESDAY WITH A
MODERATING TREND IN TEMPERATURES EXPECTED DURING THE MIDDLE AND
SECOND HALF OF THE WEEK. STRONGEST WINDS LOOK TO BE ON MONDAY OUT
OF THE NORTHWEST WITH GUSTS TO 25 MPH (30 MPH OVER RIDGES). FOR
THE REST OF THE WEEK, WINDS WILL BE ON LIGHT SIDE THANKS TO HIGH
PRESSURE OVERHEAD, BUT HUMIDITIES WILL BE MARGINALLY LOW TO NEAR
CRITICAL LEVELS. A DRY PATTERN SEEMS LIKELY TO CONTINUE WITH
LITTLE TO NO RAINFALL.
