Expected impacts:
- Scattered showers and possibly
an isolated thunderstorm can be expected before Midnight tonight
- Periods of showers and
thunderstorms are likely overnight tonight into Wednesday morning,
especially from 2am thru 10am on Wednesday
- Locally heavy downpours of rain
are possible during periods of thunderstorms, especially at times between
2am and 10am on Wednesday
- Total rainfall of 1-2 inches is
expected across the local area with this event on average, and 2-3 inches
of rain is possible possible in some spots
- Scattered thunderstorms may
redevelop in some parts of the area late Wednesday afternoon into early
Wednesday evening
Discussion:
Scattered showers and possibly an isolated thunderstorm are possible across the
local area this evening, before Midnight tonight.
It continues to appear that the timing for more widespread shower and
thunderstorm activity across the local area will be from overnight tonight into
Wednesday morning, especially from toward/after 2am through 10am on Wednesday.
Locally heavy downpours of rain are possible during periods of thunderstorms,
especially at times between 2am and 10am on Wednesday. Total rainfall of 1-2
inches is expected across the local area with this event on average, and 2-3
inches of rain is possible possible in some spots. The majority of the rainfall
will likely occur during the aforementioned 2am-10am period on Wednesday.
At this time this event does not appear likely to produce widespread flooding
across the local area, but some of the more flood prone low lying areas (i.e.,
some of the more vulnerable low water crossings and the like) may need to be
monitored at times, especially during any periods of locally heavy downpours
that are expected to occur. With the more numerous shower and thunderstorm
activity currently expected to occur between 2am and 10am on Wednesday, this
would be the most likely time period where any potential concerns could
possibly arise. Please note this includes the morning rush/transportation
period on Wednesday.
In addition...we cannot rule out the development of an isolated or scattered
strong thunderstorm overnight tonight or early on Wednesday morning, again most
likely during the aforementioned 2am-10am time period. If any such development
were to occur, strong gusty winds and spotty hail would be possible in any
affected areas. The primary concern with activity will be the locally heavy
downpours noted above, but we do want to make you aware of this possibility as
well.
Scattered thunderstorms may redevelop in some parts of the area late Wednesday
afternoon into early Wednesday evening, but at this time the extent of this
activity appears likely to be some what limited. We will continue monitoring
for any changes in this and issue updates as warranted.
We will continue monitoring the situation and issue updates as conditions
warrant.
Changes Since Last Update:
- No major changes have been
made; attempted to continue to better define various timing elements where
possible
Valid time of Advisory:
06:00 AM Tomorrow until 10:00 PM Wednesday (03/28/18)
Expected impacts:
- Scattered showers are possible
during the daytime hours on Tuesday - and an isolated thunderstorm cannot
be completely ruled out on Tuesday
- Periods of showers and
thunderstorms are likely during the pre-dawn and morning hours on
Wednesday (i.e., from 5am-12 Noon on Wednesday)
- Locally heavy downpours of rain
are possible during periods of thunderstorms, especially from 5am to 12
Noon on Wednesday
- Total rainfall of 1-2 inches is
expected across the local area with this event on average, and 2-3 inches
of rain is possible possible in some spots
Discussion:
Scattered showers are possible during the daytime hours on Tuesday - and an
isolated thunderstorm cannot be completely ruled out on Tuesday.
The most likely time period for more numerous showers and thunderstorms is
still expected to be during the pre-dawn and morning hours on Wednesday, mainly
from 5am to about 12 Noon on Wednesday.
Locally heavy downpours of rain are possible during periods of thunderstorms,
especially from 5am to 12 Noon on Wednesday.
Total rainfall of 1-2 inches is expected across the local area with this event
on average, and 2-3 inches of rain is possible possible in some spots,
especially if more than one round of thunderstorm activity is observed at a
given location. Again, this would be more likely to occur from 5am to 12 Noon
on Wednesday, based on present indications.
At this time this event does not appear likely to produce widespread and/or
organized flooding across the local area, but a few of the more flood prone low
lying areas (i.e., some of the more vulnerable low water crossings and the
like) may need to be monitored at times, especially during any persistent
periods of locally heavy downpours that may occur in some parts of the area.
With the more numerous shower and thunderstorm activity currently expected to
occur between 5am and 12 Noon on Wednesday, this would be the most likely time
period where any potential concerns could possibly arise.
We will continue monitoring the situation and issue updates as conditions
warrant.
Forecaster Confidence (Low/Moderate/High):
Moderate to High
Valid Period of this Advisory:
12:00 PM Tuesday (03/27/18) until 07:00 AM Thursday (03/29/18)
Expected impacts:
- Periods of showers and
thunderstorms are likely from mainly after 12 Noon on Tuesday through 7am
on Thursday
- Locally heavy downpours of rain
are possible at times especially with any thunderstorms during the period
- Total rainfall is expected to
average 2.5 to 3.5 inches across the local area with this event
- Locally higher rainfall amounts
are possible with any organized/persistent areas of thunderstorms
Discussion:
Periods of showers and thunderstorms are likely from mainly after 12 Noon on
Tuesday through 7am on Thursday. It will not rain during that entire period of
time, but more likely on an occasional to intermittent basis during the period.
Locally heavy downpours of rain are possible at times especially with any
thunderstorms during the period.
Total rainfall is expected to average 2.5 to 3.5 inches across the local area
with this event. Locally higher rainfall amounts are possible in spots,
especially in association with any organized/persistent areas of thunderstorms
during the period.
At this time this event does not appear likely to produce widespread and/or
organized flooding across the area, but a few locally flood prone low lying
areas (i.e., some of the more vulnerable low water crossings and the like)
could possibly need to be monitored at times especially during any persistent
periods of locally heavy downpours that may occur at least in spots across the
area. As we move closer to the even the most likely time periods for any such
concerns should become more apparent.
We will continue monitoring the situation and issue updates as conditions
warrant.
Forecaster Confidence (Low/Moderate/High):
