It'll be interesting to see how far S this front can get late in the week and next weekend. Typically they can leak farther south as convection shoots outflows south and the front jumps into them farther south. That said the overall setup is going to provide a good amount of resistance to the front as the trough in the NE races out ofb the picture and a baggy trough is left over the western SE potentially getting replaced as the 4 corners ridge reamplifies. Over time we may start to see the west coast into AK pattern change slightly which will start inching this pattern east toward the end of the month.
