Update - More chilly mornings ahead, but spring warmth is in sight!

We just have to get through the next few sunrises, and we'll end up celebrating in the afternoons.

Update - I do like a forecast that can stay relatively stable across a couple of days. To get that in early spring is a rarity (normally it's for days in the summer). However, I did want to get a quick update in there to get us into Wednesday, because the morning figures to be the coldest one we're going to get.

Record lows for the date go all the way back to a cold-snap in 1923 where the temperature was at 20° for Huntington and Charleston. Looking around the region Tuesday morning, some folks in the sheltered areas well outside the city were actually quite close to 20 itself. As I've said before on this blog, a good way of finding out the lower limit of expected temperature on calm clear nights (like we've had) is to examine the dewpoint...

Current Dew Points NAM - Forecast Dewpoints - Wednesday Morning

Current dew points are alarmingly cold this evening considering all the new plants folks may have put into the ground. Technically the growing-season hasn't begun yet because we're not beyond the first frost, but if you've already got some early season stuff in the ground (herbacious perennials, cabbage, etc.) you might want to think about covering them just to be on the safe side.

A saving grace for us is that dew points are expected to rise from the 10-degree area we're at now to about 20 when we wake up tomorrow. A low of 20 is still quite cold, but staying in the 20s is at least something. Interior Ohio and the hollers of Central West Virginia are most susceptible for getting into the upper teens.

Beyond Wednesday morning though, we'll be on a better footing for the rest of the week. Saturday will still have a chilly start, but that's a true spring day (30+ degree rise from the morning through the afternoon).

-----------------------------------

Good Tuesday morning to one and all...

As advertized, we're still unseasonably chilly to start the morning. Low temperatures will bottom out in the 20s with some frost to be seen. The National Weather Service office in Jackson, KY reported the month of March was its coldest ever (though the records date back to the 60s). Still, it's quite a contrast to one of its warmest ever the year before.

HPC - Surface Map - Tuesday

As is typical, when we find ourselves to the northeast of an approaching area of high pressure, we get the coldest influx of air and lowest morning temperatures. Since we're now in April though, the afternoon Sun is going to do wonders to warm us up-- but not exactly at first.

EKDMOS Meteogram - Huntington, WV

I don't know if I've shown a 'meteogram' before, but it's basically a graph of particular variables over the course of time as it advances forward to the right. In the above image, the green and blue represent the approximate boundaries for possible temperature variation, while the red line represents the highest likelihood values in the set for any particular time interval. At first, highs and lows are rather tight together, but the trend is for a wider range and a shift to warmer numbers later on this week. Saturday in particular features a high 'diurnal' (difference between the low and the high temperature). This also reflects some returning sunshine after a bout of showers comes through later Thursday and Friday (that keep that temperature range down to a minimum, which typically happens in clouds and showers).

The bulk of the storm system is sliding underneath us, but this time around we're not talking about snowfall. In addition, it won't take long after this one's gone to ratchet up the mild skies in time for the weekend, as the 7-Day and the above meteogram attest.
