Tuesday brought yet another June-like day in the middle of April across Pennsylvania and New Jersey, with highs in the upper 70s to around 80 degrees across much of the area. Allentown officially hit 80 degrees for the first time this year, and April 2019 (through 23 days) currently ranks as the third warmest April on record in the Lehigh Valley. Much of the day was dry and sunny, although clouds increased late in the day ahead of a weak cold front approaching from the west.
The cold front will continue to weaken as is travels east through the viewing area tonight. While we're not expecting much fanfare from this front as it moves through, we will definitely see more clouds as its passing and a few showers, perhaps with a rumble of thunder. That activity should last through the wee hours on Wednesday, at which point the front will exit our area to the east and the clouds will begin breaking from west to east. Rainfall amount won't amount to much with a few hundredths to possibly as much as a .10" expected. The clouds and added moisture in the atmosphere will stop temperatures from tumbling past the middle 50s, which is very mild for overnight lows in late April.
Despite the mild start on Wednesday, the afternoon won't be nearly as warm as it was on Tuesday. We'll still see them near 70 degrees for daytime highs, which is nothing to sneeze at in late April, but 80s aren't in the picture on Wednesday. This is because in the wake of the departing cold front high pressure will slide in from the Great Lakes bringing plenty of sunshine, but also a slightly cooler air mass with it. Along with that, there will be a bit of a breeze with wind gusting past 20 miles per hour at times.
Those winds will die down by Thursday morning as high pressure begins to slide off the East Coast quickly being replaced by a low pressure system traveling east-northeast through the Ohio River Valley. This approaching low will have very little impact on the day aside from causing the sunshine to fade from west to east during the afternoon. This means the area will experience another pleasant day overall as temperatures top out near 70 degrees for the second day in a row.
Thursday night the aforementioned low will cause showers and eventually some steadier rain to develop across the region. This will last through Friday morning and into the afternoon before the low and its cold front push exit the area to the east. While here, thunderstorms are possible but we're not expecting anything too severe to break out at this time. As for the rainfall amounts from this event, a general .50" to 1.0" is expected. That would mark the 9th consecutive Friday, dating all the way back to March 1st, in which Allentown has recorded at least a trace of precipitation. It's a fad we hope fades by next week.
By Saturday morning, Friday's rain will be long gone. In fact, we should already see some clearing Friday evening as an elongated area of high pressure builds in the west. This will result in a dry start to the weekend, but also more seasonable temperatures as highs only reach the middle 60s on Saturday.
Have a great night!
