Heat the Southwest; Fire Weather in the Central U.S.; Kona Low Impacting Hawaii

A rare March heat wave is ongoing with much above-normal temperatures over the Southwest U.S. through this weekend. Periods of critical fire weather will persist from the central Rockies to the central and southern Plains through the weekend as gusty winds and low relative humidity continue. A Kona low will continue to bring several rounds of moderate to heavy rainfall to Hawaii through Sunday. Read More >

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
Rain has exited the area this evening with some patches of 
clearing allowing for some patches of locally dense fog 
formation across central Pennsylvania. The highest probability 
for restrictions will likely remain at BFD where ample low-level
moisture has allowed for a fairly persistent IFR cloud deck 
that is expected to persist through 12Z Sat with high 
confidence. The next airfields progged for IFR restrictions 
would likely be at JST/LNS where some patches of clearing will 
allow for fog formation. There will remain a non-zero 
probability in IFR restrictions at the rest of central PA's 
airfields due to recent rainfall and some clearing; however, at 
IPT/UNV there is lower confidence in widespread long-duration 
IFR restrictions as a more expansive low-level cloud deck 
~3000ft AGL is moving across the area, with another area of low-
level (still VFR) cloud decks traversing the Susquehanna Valley
and beginning to make it into MDT. That being said, most 
uncertainty with respect to the visibility/ceiling forecast is 
honed in in the next six hours, so aviators will need to monitor
current forecast/observational trends across central PA.

Widespread improvement towards VFR is expected after 12Z 
Saturday for those airfields that experience restrictions 
overnight. BFD/JST/LNS are more likely to remain down into the 
morning hours before low-level cloud decks and any fog formation
will mix out leaving a broken deck of mid-to-high level clouds.
Fairly high confidence with respect to all airfields prevailing
VFR after 15Z Saturday and through the end of the 06Z TAF 
package.

Outlook...

Sun...Rain overspreads north to south, restrictions possible.

Mon...Rain gradually tapers off north to south, transition to 
snow possible mainly north of I-80 (BFD/IPT). Restrictions 
possible within rain/snow showers.

Tue...Mainly dry with VFR conditions. Slight chance of snow 
shower across northern PA late which could bring some 
restrictions.

Wed...Rain and snow showers across northern PA with 
restrictions possible.
