AREA FORECAST DISCUSSION National Weather Service Wilmington OH 744 PM EDT Sat Mar 30 2019 .SYNOPSIS... A dynamic system with an accompanying vigorous cold front will progress through the area this evening with rain and even a little snow. Drier and cooler conditions return tonight through Monday before a warming trend develops toward midweek with ample sunshine during the first part of the workweek. && .NEAR TERM /THROUGH SUNDAY/... The lingering corridor of rain showers left behind the initial S/W this morning continues to train from portions of southeastern IN through central OH. Although rainfall amounts have generally been light within this strip near the I-71 corridor, some locations have already picked up almost half of an inch of rain. The second and much more impressive and dynamic S/W system is currently beginning its track across the western Ohio Valley. As it pushes eastward this afternoon into this evening, a rapid uptick in forcing will allow for widespread precipitation to overspread the ILN FA from the west. This will occur with a surface cold front sagging southeast through the heart of the local area, with an increase in surface convergence leading to heavier rainfall rates during the late afternoon into the evening hours. The moisture convergence appears like it will initially focus along and north of the I-71 corridor before the main mid/upper level energy pushes far enough east to accelerate the front and begin a transition to a more progressive west to east movement late this evening. However, before that occurs, there will be a 3 or 4 hour window from approximately 5 PM to 9 PM where pockets of heavy rainfall near the I-71 corridor could lead to some localized flooding. Rainfall rates within this time frame could approach or exceed 1/3 inch per hour, with some isolated 1/2 inch per hour rates not completely out of the realm of possibilities, especially on the southern flank of the precipitation shield where instby/convective elements will be the most widespread. Past about 9PM, the main axis of forcing will begin to become a bit more progressive, allowing the axis of heaviest rain to shift from a SW-NE orientation to move of a N-S orientation as it moves generally in a ENE fashion. The potential for training convective elements in the early evening as the S/W energy interacts with the surface frontal boundary will result in ponding of water in low lying areas and could very briefly result in other localized flooding concerns. However, at this time, the duration of highest concern (about a 4 hour window) appears to be too small at this time to warrant a Flood Watch. However, it appears very possible that several shorter-fuse areal flood advisories may eventually be necessary should/rainfall rates dictate this be needed. The other main concern of the day -- and there are several of them -- will be the rapid drop in air temperatures behind the front, especially as it begins to accelerate eastward late this evening. This will allow for a better push of low level cold air, with sharp drops in temperatures anticipated with the FROPA. There continues to be a signal that there will be enough of an overlap between the moisture and low level cold air to yield a rapid changeover to either a rain/snow mix or even all snow -- particularly for parts of west-central Ohio and the northern Miami Valley eastward into northern parts of central Ohio. While the thermal profiles will be marginal at best to support any accumulation, the rates themselves may be enough to accumulate on grassy and elevated surfaces and perhaps even briefly on area roadways. There is concern in the 9 PM to 12 AM time frame from Darke County eastward through Delaware County of brief heavy pockets of snow which could reduce visibility and cause rapid, but light accumulations. The accumulations will be maximized on grassy and elevated surfaces where 1 to 2 inches will be possible. Some of this may even begin to melt after the snow stops falling (near/after midnight). At this time, the potential impacts appear to be low enough as to not warrant a winter weather advisory, but will continue to highlight threat in HWO and put out an SPS with additional details/timing. The third weather item to consider during the near term period is the non-zero threat for a few strong to severe storms late this afternoon into the early evening immediately along the leading edge of the potent frontal boundary. Current radar trends show increasing lightning within convection across western Kentucky and extreme southern IN which will move our way in the coming handful of hours. Model soundings continue to suggest several hundred J/kg of CAPE in a somewhat well- mixed BL across northern/northeastern Kentucky and far southern Ohio from about 21z to 01z before the front advances far enough east that the instability in shunted out of the ILN FA. Although convection is not expected to be particularly robust, any of the stronger cores could translate some gusty winds down to the surface in the aforementioned areas. With this, the day 1 SPC convective outlook brought a MRGL risk into parts of northern Kentucky which in a later update was subsequently expanded a bit further north/east to include parts of northeastern Kentucky and south- central Ohio, which is well- justified. Although the wind fields are not overly impressive, the advection of an increasingly moist environment into areas where surface temperatures have reached to near 70 degrees will lead to increasing low level instby through about 01z. After this point, the weak surface wave should be racing off to the east, shunting the instby east of the area and essentially ending the severe threat. And even with all of this, gusty synoptic-based winds of 30-35kts will be possible this evening immediately following the FROPA as a temporarily tight pressure gradient develops. The gustiest winds will likely be in the 2 hours immediately after the FROPA within the axis of heaviest rain on the immediate cold side of the boundary. However, gusts are expected to remain below advisory criteria -- so no wind headlines at this time. The back edge of precipitation will progress fairly quickly through the eastern parts of the ILN FA around or shortly after midnight with dry conditions overspreading the entire area for the overnight period. Strong CAA will settle in late this evening through the early overnight period, with an unseasonably cold night ahead of us as lows dip into the 20s to around 30 degrees area-wide by daybreak Sunday. && .SHORT TERM /SUNDAY NIGHT/... As active as the near term period will be, the short term period will be on the other side of the spectrum as surface high pressure settles into the western Ohio Valley by late in the day on Sunday. Steady northwest flow will be maintained, so temperatures will remain well below normal through the short term period, with highs only topping out in the low 30s (NE) to upper 30s (SW). Cloud cover will slowly erode on the SW flank through the day, yielding progressively sunny skies initially in the Tri-State area in the morning. Some cloud cover will stream off of Lake Michigan through the day, but the back edge of clouds will scatter out from SW to NE during the afternoon, with clear skies anticipated area- wide for Sunday night. Lows will bottom out in the 20s area-wide Sunday night with progressively calmer conditions settling in for the end of the short term period. && .LONG TERM /MONDAY THROUGH SATURDAY/... Period begins with deep longwave trough across eastern Canada with the main trough axis across New England. Broad northwest flow will be in place over the Great Lakes with strong surface high pressure over the Ohio Valley. This is a very dry fetch for the area thus expect plenty of sunshine to begin the week with temperatures slowly moderating. Shortwave swinging southeast will buckle the trough axis back to the west into Tuesday/Wednesday but forcing/moisture tied to this system looks to remain north of the area. On Wednesday, next upper trough over the Rockies will shift rapidly east underneath the large longwave trough over eastern Canada, which will induce height rises initially over the Ohio Valley which should continue dry weather and further moderation of temperatures. Next surface low pressure developing to our west will increase moisture transport into the Ohio Valley on Thursday with warm advection induced showers likely developing along a slowly developing warm front as it lifts north. This system ejects northeast into the Great Lakes on Friday with increasing chances for showers. Kept thunder out of the forecast for right now given marginal instability /lapse rate/ over the Ohio Valley but may need to be introduced along/south of the Ohio River in time. Temperatures into the 60s with this warm/moist southerly fetch, with showers becoming likely by Thursday night into Friday. First look at next weekend looking dry pending the timely ejection of the Friday weather system, with temperatures near normal. && .AVIATION /00Z SUNDAY THROUGH THURSDAY/... The cold front has pushed southeast of the TAF sites and will continue to clear the remainder of our area over the next couple of hours. However, widespread showers are continuing to lift northeast along the front and these will persist at the TAF sites for the next few hours. MVFR to IFR cigs and vsbys can be expected with these showers. Colder air moving in behind the front will allow for a mix and/or change over to snow later this evening from the northwest before the pcpn tapers off overnight. The most likely TAF site to be affected by this will be KDAY, but a changeover to snow will also be possible for an hour or two at the remaining TAF sites. Once the pcpn comes to an end, some MVFR cigs will linger through much of the night before some partial clearing develops late tonight into Sunday morning. However, in northwesterly low level CAA, expect to see sct to bkn VFR stratocu develop later Sunday morning and persist into the afternoon.
