.AVIATION /19Z SATURDAY THROUGH THURSDAY/...
Low/mid clouds are becoming a bit more scattered this afternoon
amongst southerly winds gusting to around 20 kt at times. MRB
does stand a chance of a thunderstorm in the vicinity through
the late afternoon. Timing of thunderstorms into the metro
terminals is more uncertain, especially given current upstream
storm placement, but still looks likely to be after 00Z. Have
placed a 4-hour VCTS group at all locations, although there is
some chance the storms do not hold together. Some showers
possibly linger through the night. MVFR conditions could develop
at MRB for several hours around dawn, whether through patchy fog
or lowered ceilings.
Sunday brings another potential active weather day, all ahead of
an approaching cold front. Right now the afternoon to early
evening would be the most likely timing of thunderstorms. These
storms appear more likely than Saturday and will pose a threat
of strong wind gusts and heavy rain. Any convective activity
should diminish by later in the evening with northwesterly flow
ensuing in the wake. For Monday, VFR conditions are expected
with northerly gusts up to 15 to 20 knots.
VFR conditions are expected Tuesday into early Wednesday before
isolated showers and thunderstorms return Wednesday afternoon and
could lead to instances of sub-VFR conditions. Southeasterly winds
on Tuesday will turn more southerly by Wednesday with afternoon
gusts 10 to 15 knots at times.
