NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
230 AM EDT SAT APR 18 2026
DISCUSSION
WELL ABOVE NORMAL TEMPERATURES AND DRY CONDITIONS ARE EXPECTED
THROUGH TODAY THANKS TO HIGH PRESSURE OFF THE SOUTHEASTERN U.S.
COAST. A COLD FRONT ARRIVING TONIGHT INTO SUNDAY WILL BRING THE
FIRST OPPORTUNITY FOR MEASURABLE RAIN IN MORE THAN A WEEK, ALONG
WITH A SHARP COOL DOWN FOR EARLY NEXT WEEK. THIS COMES WITH GUSTY
NORTHWESTERLY WINDS ON SUNDAY WHICH IS FOLLOWED BY THE POTENTIAL OF
FROST AND FREEZE CONDITIONS MONDAY NIGHT.
TEMPERATURES EVENTUALLY MODERATE THROUGH THE WEEK.
SUNDAY...WHILE SOME RAIN IS EXPECTED LATE THIS EVENING INTO SUNDAY
MORNING, AMOUNTS OF A TENTH TO TWO TENTHS 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
THOSE AMOUNTS THIS FAR OUT IS VERY DIFFICULT. FURTHERMORE, 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. GIVEN THE SHORT DURATION
OF PRECIPITATION, THE 100-HOUR FUEL MOISTURE VALUES AREN'T LIKELY TO
RISE MUCH AT ALL, IF ANYTHING; WHILE THE 10-HOUR FUEL MOISTURE
LIKELY RISES CONSIDERABLY, BUT DROPS QUICKLY THROUGH THE DAY DUE TO
THE DRYING EFFECTS OF STRONG WINDS AND RAPIDLY LOWERING HUMIDITY.
REST OF NEXT WEEK...MUCH COOLER TEMPERATURE 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.
