DISCUSSION
ISSUED AT 122 AM EDT TUE APR 7 2026
CURRENTLY, MID/UPPER TROUGHING IS CENTERED TO OUR NORTHEAST WITH A
CANADIAN HIGH DIVING INTO THE NORTHERN U.S. AHEAD OF THIS CANADIAN
HIGH, A COLD FRONT IS MOVING THROUGH OUR REGION. WITH THE LACK OF
MOISTURE, THE MAIN RESULT WILL BE NORTHERLY FLOW AND A CONTINUATION
OF COOLER AND DRIER CONDITIONS. LOW RELATIVE HUMIDITY VALUES IN THE
20S ARE EXPECTED AGAIN TODAY. BY TONIGHT, THE HIGH WILL BE CENTERED
OVER THE EASTERN GREAT LAKES, LEADING TO STRONGER SUBSIDENCE AND
LIGHTER WINDS IN OUR AREA. PATCHY FROST WILL BE MORE LIKELY INTO
WEDNESDAY MORNING, ESPECIALLY IN NORTHEASTERN PARTS OF THE AREA.
HEIGHT RISES WILL PROMOTE THE START OF A WARMING TREND ON WEDNESDAY
WITH CONTINUED DRY CONDITIONS DURING THE DAY. BY THURSDAY, THE FLOW
ALOFT WILL BECOME MORE ZONAL WITH HIGH PRESSURE HAVING PUSHED OFF
TO THE EAST. THIS WILL KEEP CONDITIONS DRY AND SEASONALLY MILD.
FRIDAY THROUGH THE WEEKEND, THE PATTERN WILL BECOME MORE AMPLIFIED
AS A PACIFIC TROUGH WITH STRONGER UPSTREAM FLOW MOVES ONSHORE. THIS
WILL LEAD TO INCREASING RIDGING ACROSS THE EASTERN U.S., FURTHER
ENHANCING THE WARMING TREND FROM LATE IN THE WEEK. A SYSTEM IS
EXPECTED TO DEVELOP IN THE NORTHERN GREAT PLAINS SUNDAY INTO MONDAY,
BUT HIGH PRESSURE WILL KEEP OUR REGION DRY. THE RESULT WILL BE
INCREASING SOUTHERLY FLOW AND TEMPERATURES RISING WELL INTO THE
80S.
