the area of light rain is shrinking around fargo, but will likely
hold together weakly overnight. It may also start to expand again
closer to morning.
Short term (this evening through Thursday)
issued at 248 pm cdt Wed jun 19 2019
strong 500 mb low over SE british columbia this aftn will advance
slowly east and be over far southern alberta by 00z fri. An
additional short wave trough was located this aftn in south
central nd into central sd with an area of rain associated with
it. Far eastern edge of light rain is over lisbon forman nd areas.
But this short wave trough will weaken gradually tonight with the
rain area only slowly advancing east north thru the night with
precipitation weakening. However, enough threat for precip to make
it to fargo and to just west of grand forks to include some pops
tonight in this area of nd, with highest far SW fcst area.
Before then, though there have been a few light rain showers
develop and move westward with the low level flow from bemidji to
crookston area. This will dissipate at dark.
For Thursday, a shortwave trough associated with the areas of low
pressure to the west will progress into the area, leading to
widespread precipitation chances, mainly over the north dakota
portion of the fcst area. Occlusion within the system will keep
much of the conditions to be showers with a few embedded
thunderstorms. Precipitable water values are expected to be near 1
inch, which is not anomalous for the region during this time of
the year. These values, combined with the slow-moving nature of
the system, suggest some soaking rains but limited flooding
Long term (Thursday night through Wednesday)
issued at 248 pm cdt Wed jun 19 2019
rain shower band to weaken over NW mn Thu night.
Friday to Sunday...
the earlier portion of the long term is dominated by the progression
of the low pressure system with meridional flow aloft. Guidance
suggests that much of the area will be on the east side of the upper-
level trough with southerly winds near the surface on Friday.
Potential does exist for some stronger storms later in the day as
models suggest negative LI values and 0 to 6 km shear values of 20
to 40 knots. However, uncertainty still exists at this point. The
slow-moving trough will keep this pattern continuing into Saturday
and possibly Sunday with more chances for showers and storms.
Seasonal temperatures will continue through the weekend as well.
Monday through Wednesday...
as the trough progresses to the east, look for continued chances of
precipitation on Monday with seasonal temperatures. Following the
system's movement to the east, models indicate some ridging over the
area for Tuesday and Wednesday. This pattern suggests a warming
trend is possible with many areas reaching into the 80s. Increased
moisture also says some isolated convection is possible, but a large
amount of uncertainty exists for this time frame.
Aviation (for the 06z tafs through 06z Thursday night)
issued at 1145 pm cdt Wed jun 19 2019
pretty much kept with the previous TAF set. Main change was to
lower afternoon wind speeds a little bit. Otherwise, expect
ceilings to lower on Thursday as the next batch of rain, possibly
mixed with thunder, moves in. This should happen first at kdvl,
but will take longer at the other TAF sites. Do not think it will
be heavy enough to result in lower vsbys.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
