KEY MESSAGE 1: Increasing heat risk through late week

Seasonably warm and dry conditions today will be replaced by
building heat and humidity through late week along with an
increasing threat for localized heavy downpours/thunderstorms.

Thursday is projected to be the hottest day of the week with
fcst max heat index values most likely reaching advisory
criteria thresholds east of the Allegheny Mtns. Max temps are
fcst to approach daily records in a few locations Thu/Fri. The
early season/mid-June sweltering heat should slowly ease by
early next week.

&&

.AVIATION /12Z MONDAY THROUGH FRIDAY/...
Two areas of lower ceilings associated with a backdoor cold
front are likely to bring low-end VFR ceilings to BFD/MDT/LNS
through ~14Z Monday, with very high (> 90%) confidence in VFR
conditions prevailing through 12Z Tuesday. Recent HREF guidance
does indicate a slow progression of a high-level cloud deck
after ~06Z Tuesday and have timed out these mentions in the most
recent TAFs with no restrictions and this deck will likely aid
in preventing fog development Monday night into Tuesday. Light
winds are forecast throughout the entire TAF package with high
(~80-90%) confidence under the influence of high pressure at the
surface.

Outlook...

Tue...VFR favored outside of isolated morning fog. Restrictions
possible in -SHRA/-TSRA late.

Wed-Fri...Restrictions possible in -SHRA/-TSRA.

&&

.CTP WATCHES/WARNINGS/ADVISORIES...
None.
