What happened

The episode as NWS CTP wrote it up.

Severe (D2) drought remained across portions of southern Pennsylvania throughout the month with near-to-slightly below average precipitation values observed across much of the region throughout May 2026. One area that received above average precipitation was across southern Fulton County which allowed for the county to be removed from severe drought towards the end of the month. Elsewhere, Franklin County remained under a Drought Warning while Lancaster County remained in a Drought Watch from the Pennsylvania Department of Environmental Protection.

.DISCUSSION...
KEY MESSAGE 1: Cool and unsettled pattern to end April and
start May with shower chances and frost/freeze risk through the
weekend

Several disturbances rotating around a persistent upper level
closed low centered over Ontario and Quebec will help to
reinforce broadly deep troughing across the eastern U.S. through
much of next week. This pattern will keep conditions cool and
unsettled at times as multiple frontal systems move through. In
addition to shower chances, the fronts will bring reinforcing
surges of cool air, keeping temperatures near to below seasonal
averages. Chilly nighttime lows will also lead to frost and
freeze concerns Thursday-Saturday night, particularly now that
the growing season is now active across all CPA zones.

Upper level flow briefly becomes more zonal tonight and weak
ridging develops below 700 mb behind a disturbance bringing
scattered showers to the region this afternoon, which should
help to clear out much of the cloud cover over the region. This
combined with light winds should be supportive of radiational
cooling and temperatures should fall into the 30s across all of
central PA. While there could still be a few clouds over the
northwest, confidence in frost and freeze conditions has
increased. As a result, the Frost Advisory has been expanded a
tier of counties to the east, and was upgraded to a Freeze
Warning for Elk, McKean, and Potter Counties.

The next shortwave rotating through the broad upper trough will
bring a round of showers to the region during the day tomorrow,
but we again expect to see enough clearing overnight for frost
and freeze concerns to develop. The coldest night across
northern and western parts of the forecast area will be Saturday
night with a freeze almost certain, but there is some
uncertainty regarding the southeastward extent of frost as
there will be a rather tight pressure gradient across the region
due to a developing area of low pressure off of the coast.

Temperatures trend warmer for the beginning of next week, but
all guidance indicates that unsettled weather will continue with
multiple chances for rain.

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
Rain is slowly exiting the region this afternoon with a few
isolated showers still present across the state. These will
dwindle over the next hour or so with clouds and skies clearing
by 06Z. The only terminal that has a potential for MVFR or IFR
conditions overnight will be BFD. Elsewhere should remain VFR
overnight with high confidence. Winds will continue to be
moderately gusty (high teens to low 20s (KTS)) for a few more
hours this evening before calming by 06Z everywhere.

Another round of rain will move across the area on Friday, with
accompanying MVFR ceilings expected at BFD and possible (50%)
at IPT, UNV, JST, and AOO. Rain showers will eventually make it
towards the south east, but coverage will be isolated at best.

Outlook...

Fri-Sat...Mainly VFR with brief restrictions possible in
showers.

Sun...Restrictions possible northwest in -RA and possibly some
-SN.

Mon... Models hinting at another low pressure wave to our west,
precip may lead to restrictions, particularly in the west.

.CLIMATE...
*Daily record rainfall of 1.18 inches at KJST yesterday 4/29
 breaking the previous record of 1.13 inches set back in 1964
*Despite a cool end to the month, April 2026 will end as one of
 the warmest on record

Drought, Franklin

When
May 1, 12:00 AM EST to May 31, 11:59 PM EST
Where
Franklin forecast zone
Reported by
Drought Monitor
Coordinates
39.927, -77.721 (the zone’s center; the record gives no point)

Severe (D2) drought conditions persisted across south-central Franklin County through May 2026. Precipitation for the month of May 2026 largely remains near climatological averages for much of the county; however, prolonged dry conditions over many months allowed for drought conditions promoted continuation of severe drought conditions. A Drought Warning remained in effect by the Pennsylvania Department of Environmental Protection for the entire month with voluntary water restrictions in place across portions of the county.

Drought, Fulton

When
May 1, 12:00 AM EST to May 26, 7:00 AM EST
Where
Fulton forecast zone
Reported by
Drought Monitor
Coordinates
39.925, -78.113 (the zone’s center; the record gives no point)

Severe (D2) drought conditions persisted across southern Fulton County throughout much of May 2026 before conditions began to improve by the end of the month due to heavy rainfall. Well-above average precipitation, centered across southern Fulton County during the middle of the month allowed for improvement of the severe drought across the region, with Fulton County being taken out of severe drought on May 26th. The Pennsylvania Department of Environmental Protection kept a Drought Warning in effect for the entire month of May 2026.

Drought, Lancaster

When
May 1, 12:00 AM EST to May 31, 11:59 PM EST
Where
Lancaster forecast zone
Reported by
Drought Monitor
Coordinates
40.042, -76.248 (the zone’s center; the record gives no point)

Severe (D2) drought conditions persisted across much of Lancaster County through May 2026. Precipitation for the month of May 2026 largely remained near climatological averages for much of the county; however, prolonged dry conditions over many months allowed for drought conditions promoted continuation of severe drought conditions. A Drought Watch remained in effect by the Pennsylvania Department of Environmental Protection for the entire month.
